FileRoller does not install related contracts

### What Happened?

While investigated a file-roller related issue, the contracts related to that app and the app were deleted. When FileRoller was reinstalled with AppCenter the contracts were not restored. In order to reinstall both the app and the contracts the `deb` package `org.gnome.FileRoller` had to be installed from the terminal.

### Steps to Reproduce

1. Uninstall `org.gnome.FileRoller` with apt
2. Reinstall FileRoller with AppCenter - the contracts are not reinstalled

### Expected Behavior

Not sure what to do about this (if anything) but it seemed unsatisfactory that `apt install org.gnome.FileRoller` and `flatpak install org.gnome.FileRoller` should unexpectedly give different results when the packages have the same name. May be the contract(s) should be supplied in a different more obviously described package/Flatpak so that a search for "file roller" in AppCenter shows both the app and the contracts and both can be installed from AppCenter.
