ubuntu-bug cannot report a problem with the preinstalled snap-store

With the move to package the software center as a Snap in 20.04, I decided to go fishing for bugs that might manifest on my 18.04 machine (with a home directory outside of /home), which has trouble with snaps, when I get around to upgrading. I set up this 20.04 VM, moved the home directory for the user, and tried to run `snap-store`. It didn't work.

So I went to report a bug with it:

    ubuntu-bug snap-store

This didn't work. Instead of the normal Apport report interface, I got a dialog that says:

    The problem cannot be reported:

    This report is about a snap published by canonical. No contact address has been provided; visit the forum at https://forum.snapcraft.io/ for help.

If the snap-store is part of the base system, and is indeed the recommended package manager in 20.04, and Canonical published it, ubuntu-bug ought to work on it.
