appDisplay: Stop watching FolderIcon parent view when destroyed

When a FolderIcon is opened, it asks the parent view to allocate
space for it, which takes time.  Eventually, the space-ready
signal is emitted on the view and the icon can make use of the new
space with its popup.  If the icon gets destroyed in the
interim, though, space-ready signal handler still fires.

This commit disconnects the signal handler so it doesn't get called
on a destroyed icon.
