hr_attendance: You cannot sign out if you change task after sign in

hr_attendance: You cannot sign out if you change task after sign in (OpenERP 5.0 last stable).

If you do these sequence of actions:

1) Sign in (Menu HR - Attendances - Sign in / Sign out or Sign in / Sign out by project)
2) Change your work (Menu HR - Attendances - Sign in / Sign out by project, fill analytic account and work description and press Change work button
3) Now you are not be able to sign out

You must go to menu Attendances / Attendances and delete the last one with field Action='Action' to be able to sign out.

This can be fixed if lines 117 and 140 in hr_attendance/wizard/sign_in_out.py are changed from:

    att_id = service.execute(cr.dbname, uid, 'hr.attendance', 'search', [('employee_id', '=', emp_id)], limit=1, order='name desc')

to

    att_id = service.execute(cr.dbname, uid, 'hr.attendance', 'search', [('employee_id', '=', emp_id), ('action', '!=', 'action')], limit=1, order='name desc')
