Return remote errors from FS.PerformJoin (#1164)
* Return remote errors from FS.PerformJoin

Follows the same pattern as PerformJoin on roomserver (no error return).

Also return the right format for incompatible room version errors.

Makes a bunch of tests pass!

* Handle network errors better when returning remote HTTP errors

* Linting

* Fix tests

* Update whitelist, pass network errors through in API=1 mode
