The behavior of the back/forward history of file-roller is inconsistent with
other programs.
Steps to reproduce:
1. Open an archive with a directory structure.
2. Open a directory in that archive.
3. Press the back button.
4. Open a different directory.
5. Press the back button twice. Notice how you are in the directory you opened
in step 2.
Other programs that have back/forward viewing history would remove the first
directory from the viewing history since a new directory was opened after
pressing back.
