Remove debug leftovers from a test. (#314)
* Remove debug leftovers from a test.

This is really terrible and has meant whenever anyone has run `yarn test:integration` they have only been running this test.
💀💀💀
https://www.youtube.com/watch?v=jmX-tzSOFE0

* Set a default timeout for integration tests that is 5 minutes long.

Seriously, I don't think there is much to gain by making people guess
a reasnoble time for a test to complete in all the time, especially
with how much Synapse changes in response time and all of the machines
involved in running these tests.

* Warn when giving up on being throttled

* For some reason it takes longer for events to appear in /state

no i am not going to track down why yet.

* Rate limiting got a lot more aggresive.

https://github.com/matrix-org/synapse/pull/13018

Rate limiting in Synapse used to reset the burst count and remove
the backoff when you were spamming continuously, now it doesn't.
Ideally we'd rewrite the rate limiting logic to back off for longer
than suggested so we could get burst again, but for now
lets just unblock CI by reducing the number of events we send in these
tests.
