Review request for Plasma, David Edmundson, David Faure, and Hugo Pereira Da

Changes
-------

Submitted with commit 23e54baa3cf1258b5d105c22609103d13868583f by Hugo Pereira 
Da Costa on behalf of Peter Wu to branch Plasma/5.7.


Bugs: 356940
    https://bugs.kde.org/show_bug.cgi?id=356940


Repository: breeze


Description
-------

Since Qt 5.6.0, Qt5 applications started crashing on exit. All signs
point to this delete-on-destroy hack which was added to avoid outliving
the plugin lifetime.

This method is wrong because the returned style is owned by the caller
(QApplication, QProxyStyle, etc) and will cleaned up when those users
are destructed.

Testing
-------

Ran the updated test.sh from "Testcase (ASAN) with normal QApplication::quit 
and exit()" from bug https://bugs.kde.org/show_bug.cgi?id=356940, no longer 
crashes. Tested with Qt 5.7.0.


Thanks,

Peter Wu
