autopilot tests are creating many Touch devices without closing them

This is a result adding one test without closing devices: http://jenkins.qa.ubuntu.com/job/generic-mediumtests-runner-mako/4538/console
(1 failure)

This is the same branch but closing the devies: http://jenkins.qa.ubuntu.com/job/generic-mediumtests-runner-mako/4539

Fix committed into lp:unity8 at revision None, scheduled for release in unity8, milestone phone-v1-freeze

This bug was fixed in the package unity8 - 7.84+14.04.20140128-0ubuntu1

---------------
unity8 (7.84+14.04.20140128-0ubuntu1) trusty; urgency=low

  [ Michal Hruby ]
  * Added unity-scope-tool, which will help when developing scopes.

  [ Michał Sawicz ]
  * Added unity-scope-tool, which will help when developing scopes.
  * Use full DashContent, not just GenericScopeView in ScopeTool.qml.
  * Bring Card and CardHeader over from new-scopes.
  * Work around bug #1268578. (LP: #1268578)
  * Drop unnecessary version dependencies.
  * Return null instead of undefined from findChild and
    findInvisibleChild.
  * Fix CardHeader and Card heights (empty Label does have non-zero
    height apparently). Also improve test robustness and reduce future
    diffs.

  [ Albert Astals ]
  * Do not assert if the item we are removing was not created yet
    (because e.g. it's not in the viewport).
  * Position correctly the pointer of the search history box .
  * Make test_filter_expand_expand less unstable in CI VMs Make sure
    header0 is the header0 we want to click On the CI VM stuff is a bit
    slower than on real hw and we were clicking in the wrong place.
  * Add TabBar to the Dash header navigation Changes this comes with: *
    DashBar at the bottom is gone * PageHeader doesn't have a Label
    anymore, it has the childItem property where you add which thing it
    has to contain * New: PageHeaderLabel mimics the old behaviour of
    PageHeader * The header of the LVWPH of GenericScopeView is now fake
    and only used for positioning. There is a single global floating
    header in DashContent (which is a PageHeader with a TabBar as
    childItem) * The GenericScopeView previewLoader and OpenEffect have
    been also moved to the DashContent so that the openEffect includes
    the floating header in the "animation" .
  * Introduce the HorizontalJournal.
  * If there are no items m_firstVisibleIndex has to be -1 .
  * Add some more documentation about tests to the CODING file.
  * Fixes to the journal cmake tests code * Output to the correct
    filename for the test * Don't output stuff from the tryXYZ targets.
  * Adapt to findChild return value changes .
  * Organic Grid for the Dash View.
  * Misc journal fixes Don't init *modelIndex to INT_MAX Makes no sense
    since we're not doing any qMin and the calling function also accepts
    any index >= 0 as valid so in some cases it may end up wanting to
    create an index that doesn't exist Don't refill if height() < 0,
    that gives bad ranges for from/to and the code gets confused .

  [ Michał Karnicki ]
  * Fix grid view column count.
  * Add test for minimum number of items in a carousel.

  [ Allan LeSage ]
  * Add stubs for indicators autopilot tests.

  [ Andrea Cimitan ]
  * Avoid input falling through notifications onto surfaces below, thus
    fixing LP: #1257312. (LP: #1257312)

  [ Leo Arias ]
  * Close the Touch devices after the tests. (LP: #1267600)
  * Added methods to scroll to other scopes on autopilot tests.
  * Added autopilot helpers for the app scope and the app preview.
    Install the fake scopes in order to use them on the tests. (LP:
    #1269114)
  * On autopilot hel...
