Git.pm: add comment pointing to t9000

parse_mailboxes should probably eventually be completely equivalent to
Mail::Address, and if this happens we can drop the Mail::Address
dependency. Add a comment in the code reminding the current state of the
code, and point to the corresponding failing test to help future
contributors to get it right.
