Re-enable OTP sign in on trunk by reverting most of 147297.

I am not simply reverting 147297 because that CL included some js code for correctly handling errors in the ASP case, and that is still useful should the user decide to go back to ASPs.

Change that disabled OTP on trunk:

BUG=137772
TEST=Signing in should ask for OTP instead of ASP.
