permission-reset doesn't remove document permissions

[BryanQuigley]

Ubuntu 18.04 / Stock

1.6.3

flatpak permission-reset app appears to reset permissions, but appears to do nothing.

Steps to reproduce

1. Using Firefox flatpak Open /etc/passwd with Ctrl-O.
2. Note name file:///run/user/1000/doc/4fab1618/passwd
3. Close Firefox
4. Run flatpak permission-show org.mozilla.firefox (note how it exists)
5. Run flatpak permission-reset org.mozilla.firefox
6. Run flatpak permission-show org.mozilla.firefox (note how that permission is gone)
7. Try opening file:///run/user/1000/doc/4fab1618/passwd again. Note how it still works. (IMU this should not work anymore...). Try Ctrl-F5 to try a force refresh.

Tried to reproduce this with permission-remove instead of permission-reset but I seem to have hit another bug:

$ flatpak permission-remove documents aa93c5ae org.mozilla.firefox
