Fix bunch of other segfaults due to null screens
This was motivated by a real segfault:
#0 QScreen::handle (this=0x0)

...at which point I tried to stop playing the
get-backtrace-patch-rebuild-repeat cycle and looked at the stuff which
looked fishy to my untrained eye. So this is speculative in nature, but
