Revert "Added some more debug messages."

Fallback doesn't work at this level as the change of destination isn't communicated to the source region/viewer
Reverting because this introduces a bug when access does fail.
More detail in revert of main commit.

This reverts commit ec32c1d4b69e4219fe44a38bcbc411e7996641f1.
Revert "Make HG logins fall back to fallback regions if the desired region fails."

This is very similar to my earlier revert in bcb8605f8428a9009a2badf9c9eed06d9f59962c and fails for the same reasons.
Reverting this change because it causes a problem if access is denied to the user.
This reverts commit c7a8afbb8da40e09252d58d95c89b8a99a684157.
