Fix another crash due to BufferView::last_inset_ being an invalid pointer.

Do not clear the mouse_hover state from anywhere else then BufferView, such that the last_inset_ pointer gets nulled. Besides, there is no reason to clear the mouse_hover state on collapsing the Inset.

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