mod_http_oauth2: Fix treatment of 'redirect_uri' parameter in code flow
It's optional and the one stored in the client registration should
really be used instead. RFC 6749 says an URI provided as parameter MUST
be validated against the stored one but does not say how.
Given that the client needs their secret to proceed, it seems fine to
leave this for later.
