Code review comment for ~jugmac00/launchpad:prevent-email-disclosure

This looks good as far as it goes.

https://git.launchpad.net/launchpad/tree/lib/lp/soyuz/mail/binarypackagebuild.py#n166 isn't a problem: an SPR's creator is a single person.

The importer in https://git.launchpad.net/launchpad/tree/lib/lp/translations/scripts/po_import.py#n145 sometimes ends up being ~rosetta-admins, which is a large team, so let's add a loop there.

https://git.launchpad.net/launchpad/tree/lib/lp/translations/scripts/translations_to_branch.py#n297 is marginal, but I'd be inclined to leave it alone, at least for now; I think the case where a team explicitly owns something is a bit different from the mirror-admins and rosetta-admins cases where the ownership is rather more, um, ambient.
