Add a missing "GROUP BY" to MailQuery when querying for multiple recipients

Browse source 
Summary:
See <https://discourse.phabricator-community.org/t/mail-details-view-broken/4315>. The change in D21400 detects a missing "GROUP BY" in some variations of this query.

Specifically, we may join multiple recipient rows (since mail may have multiple recipients) and then fail to group the results.

Fix this by adding the "GROUP BY". Additionally, remove the special-cased behavior when no authors or recipients are specified -- it's complicated and not entirely correct (e.g., may produce a "no object" instead of a policy error when querying by ID), and likely predates overheating.

Test Plan:
  - Disabled `metamta.one-mail-per-recipient` in Config.
  - Generated a message to 2+ recipients.
  - Viewed the message detail; queried for the message by specifying 2+ recipients.
  - Viewed the unfiltered list of messages, saw the query overheat.
