Remove third party auth redirect URI domain check.

Remove third party auth redirect URI domain check.
Talkgadget can redirect the user to other subdomains, and our content script won't run over the intermediate 302 pages, only the final URL - so we can't assume that the actual redirect URI we'll receive will match the one we asked for. Note that there is still an implicit restriction that this must be a talkgadget subdomain (since that's our content script's url glob).

Old code coped with an empty responseUrl - don't we still need to cope with
that, e.g. w/ the URL not containing a '#' character?

being pedantic: the new code was also (accidentally) coping with those cases
(substring would return "" in either case)

But given that an empty string is a special case (appsv2 will send that when the
user closes the window without authenticating), yeah, we should handle it more
clearly.
