sync: temp fix for ShowErrorUI
sync: temp fix for ShowErrorUI

If there's an auth error, and the user clicks a signin link, show the login dialog straight away.
Before this, the code would make a generic "ShowSetup" call with "NONFATAL_ERROR", resulting
in infinite spin.

BUG=91286, 92265
TEST=change gaia password for active sync account that is ASP enabled. observe error in UI, sign back in. dialog should dismiss on success.
