X11: Fix panic when dropping window before running event loop (#694)

Browse source 
Fixes #691

Dropping a window before running the `EventsLoop` results in events
still being queued when `XDestroyWindow` is called, so events like
`XI_Enter` (the culprit in this case) will still be processed.
Simply checking that the window still exists before calling
`query_pointer` was enough to solve the problem.
