fix redirect messaging

[bugfood]

If --ignore-redirects is set, then a line of code several lines above here is assigning:

server = args.server

...so the conditional 'server != args.server' is only met when --ignore-redirects is unspecified.

Note that the conditional removed in this commit was also backwards, so prior to this change, gp-saml-gui would print the wrong message when --ignore-redirects was not specified.

This change removes the message:

IMPORTANT: During the SAML auth, you were redirected from <foo> to <bar>, however the redirection was ignored because you specified --ignore-redirects

I don't think we need that message; if the user specifies --ignore-redirects, then I think the program doesn't need to say that it's doing as requested.

I could easily change that if desired, though; please let me know.

Thanks,
Corey

The test failure seems to be unrelated.
