fedsender: tolerate dupe membership events (#1824)
* fedsender: tolerate dupe membership events

Previously if the fedsender got a duplicate membership event it would cause
the entire process to crash. Now it doesn't. This masks an issue with the
roomserver where it can emit duplicate membership events.

* Update joined_hosts_table.go

Don't hold destination queues in memory forever (#1769)
* Don't hold destination queues in memory forever
