1. Previously gaia::CanonicalizeEmail(..) didn't handle upper case gmail correctly.
e.g.:  CanonicalizeEmail("USER.NAME@GMAIL.COM") previously return
"user.name@gmail.com". Instead it should return "username@gmail.com".

2. When input is not a valid email, instead of triggering NOTREACHED,
it now returns the input in lower case. In this way, the downstream use of this
method can be more flexible.
