Fixes #5582

Fix sync tightloop bug.

Don't update the ratelimiter before sending a 3PID invite

If we do the opposite, an event can arrive after or while sending the email and the 3PID invite event will get ratelimited.

This would cause emails being sent, but Synapse responding with a 429 when creating the event. The client would then retry, and with bad timing the same scenario would happen again. Some testing I did ended up sending me 10 emails for one single invite because of this.
