mod_http_oauth2: Improve handling of redirect_uri matching and fallback Per OAuth 2.1, the client MUST provide a redirect_uri explicitly if it registered multiple. If it only registered a single URI, it may be omitted from the authorize request.

This module discards typing notifications sent to a bare host JID,
preventing error replies to be sent. These errors are harmless but can
be annoying sometimes if your client shows them prominently.
