Martin Gräßlin 51ee514227 [plugins/qpa] Add a dummy screen on startup
Qt has problems initializing everything correctly if there is no screen
at startup. E.g. the breeze widget style tries to initialize some pixmaps
and this fails. In worst case hitting asserts in Qt (debug build).

This change creates a dummy screen which gets destroyed as soon as there
is a real screen.
