[gnome-boxes] Remove display enter/leave notify handler

[Marc-Andre Lureau <malureau src gnome org>]

commit 6dd53baf08b5136d2aef3dfbbcf8d1d29d047737

    Remove display enter/leave notify handler
    
    This handler was required only when auto-hiding the toolbar in window
    mode. In fullscreen mode, it only contributes to wrongly stopping
    timers.
