Ensure only one transaction is used for RS input per room (#2178)
* Ensure the input API only uses a single transaction * Remove more of the dead query API call * Tidy up * Fix tests hopefully * Don't do unnecessary work for rooms that don't exist * Improve error, fix another case where transaction wasn't used properly * Add a unit test for checking single transaction on RS input API * Fix logic oops when deciding whether to use a transaction in storeEvent
