Rather than use a bulk insert via Django, use the faster `bulk_insert_all_ums` that we already have. This also adds a `ON CONFLICT` clause, to make the insert resilient to race conditions. There are currently two callsites, with different desired `ON CONFLICT` behaviours: - For `notify_reaction_update`, if the `UserMessage` had already been created, we would have done nothing to change it. - For `do_update_message_flags`, we would have ensured a specific bit was (un)set. Extend `create_historical_user_messages` and `bulk_insert_all_ums` to support `ON CONFLICT (...) UPDATE SET flags = ...`.
