Just spotted a segfault when destroying a GtkWindow after calling
g_application_quit() :

Process terminating with default action of signal 11 (SIGSEGV)

gtk: gtkapplication: fix segfault

When destroying a window associated with a GtkApplication after calling
g_application_quit() you might get the following segfault :

Process terminating with default action of signal 11 (SIGSEGV)
 Access not within mapped region at address 0x0
   at 0x5158770: gtk_application_impl_window_removed (gtkapplicationimpl.c:97)
   by 0x5155AEF: gtk_application_window_removed (gtkapplication.c:723)
   by 0xAA5DD32: g_cclosure_marshal_VOID__OBJECTv (gmarshal.c:2102)
   by 0xAA5B083: _g_closure_invoke_va (gclosure.c:864)
   by 0xAA75260: g_signal_emit_valist (gsignal.c:3272)
   by 0xAA758B1: g_signal_emit (gsignal.c:3419)
   by 0x53D7580: gtk_window_release_application (gtkwindow.c:3447)
   by 0x53E4BCB: gtk_window_destroy (gtkwindow.c:5690)

This patch stops listening to window events once the GtkApplication is
shutdown.
