Subject: Fix crash when removing an ancestor of the current folder (bug #8168).

Whenever we release the GFileMonitor of a ThunarFolder, we also need to
disconnect from its signals. Otherwise one of the signal handlers might
still be called, potentially with corrupted user data (which was the
case here).
