monitor: improve unmount detect heuristic
Detect when an unmount happens and a subfolder of the mount is displayed. The previous solution did a GMount pointer compare, but this was not working in any case. This patch fixes is by comparing the removed mount root with the currently monitored location. This fixes a regression since 0852847e. https://bugzilla.gnome.org/show_bug.cgi?id=724560
