fix(express): Incorrest uses of 400 error codes (#1553)

Fixes incorrest usage of 400 HTTP responses being returned from the
server, in favor of using 422.

Also, changed a few return codes to 401 where it was more appropriate.

See this article for reasoning behind moving to 422, and why 400 isn't
appropriate for these cases.
