Consolidation of roomserver APIs (#994)

* Consolidation of roomserver APIs

* Comment out alias tests for now, they are broken

* Wire AS API into roomserver again

* Roomserver didn't take asAPI param before so return to that

* Prevent roomserver asking AS API for alias info

* Rename some files

* Remove alias_test, incoherent tests and unwanted appservice integration

* Remove FS API inject on syncapi component
