Incorrect package rename handling causes file overwrite errors on upgrade

I got a report from an user that he gets the following error messages when upgrading:

When renaming packages like here from qtdeclarative5-qmltermwidget1.0 to qml-module-qmltermwidget1.0 and the pamauthentication package, you need to provide a transitional package with the old name that then is Breaks + Replaced by the new package name, see example at bug #1342031.
