Fix a crash due to Inset**::mouse_hover_[] containing an invalid pointer to a BufferView.

Browse Source 
Clear the mouse_hover state when closing the BufferView. Otherwise, there will be an invalid pointer stored in the Inset and crashing LyX when the Inset's destructor is called.

See also r33908, r34117, r34348, r34353, r34354, r34363 and bug #3900.
