reconsiderOutputs() may be called before the async config fetching
operation (KScreen::GetConfigOperation) has finished, so the pointer is
still null at that point. This can happen if qApp::screenRemoved fires
before kscreen was able to start the backend loader and pass back a
ConfigPtr.
The bug is rooted by in the dual-use of libkscreen and qApp's QScreen
handling. The timings here produce this race condition. This patch
should be quite safe, though, since it doesn't change the logic, but
rather makes sure this race condition bails out nicely by falling back
to just waiting until a kscreen config has arrived (which will happen
right after).
