Emit redacted_event from the roomserver when redactions are validated (#1186)
* Emit redacted_event from the roomserver when redactions are validated - Consume them in the currentstateserver and act accordingly. - Add integration test for the roomserver to check that injecting `m.room.redaction` events result in `redacted_event` being emitted. * Linting * Ignore events that redact themselves
