View not updated when grandparent directory is trashed

Steps to reproduce:

• mkdir -p a/b;touch a/b/somefile
• Open two thunar windows, on current folder and in b
• right-click on a --> move to trash (or trash a via console )

Result: "somefile" will still be shown.

Note that for trashing the direct parent, things work fine

Note that for "delete", this bug does not exist
