Encode redirect URL value

[2m]

I am not completely sure why does encodeRedirectURL not handle this. Documentation for this method states that it tries to determine whether encoding is needed or not. And for some reason it does not encode provided redirectURL.

When redirectURL is not encoded, only the first argument (code) is then taken from the URL in the /link endpoint.

When redirectURL is encoded, both code and state is parsed from the URL correctly and Google endpoint does not complain about missing state argument anymore.
