Update Events call-sites which now don't return an error, update parsedRespState to sort (#2227)

Browse Source 
* Topologically sort with `SendEventWithState`, so that earlier events should satisfy auth for later ones

* Revert "Topologically sort with `SendEventWithState`, so that earlier events should satisfy auth for later ones"

This reverts commit b0cd706012b4c9b6724b11e16f19c4cb732ab286.

* Update to matrix-org/gomatrixserverlib#293

* `Events` no longer returns an error, other tweaks

* Make sure `Events` is sorted for `parsedRespState` too
