QGuiApplication: revert b8d0fac5a9 (mouse event handling)

The current attempt to fix the problem described in b8d0fac5a9
has shown to have unforeseen issues. The assert in the
patch has been triggered in user code (see bug report), which, when
looking more closely, shows that the assert cannot be guaranteed
for all cases. E.g if user code (or Qt drag'n'drop code) starts a new
event loop upon receiving the move event, this can deliver new mouse
events before the move returns, which will trigger the assert.

So it seems like the most correct solution is to *post* the second button
event after all (directly trailing the move event), to at least make sure
mouse events are being delivered in the correct order. The crash that caused
the original change will need to be fixed by other means.
