fix a potential race condition for pre-login and ext auth 
hooks

doing something like this:

err = provider.updateUser(u)
...
return provider.userExists(username)

could be racy if another update happen before

provider.userExists(username)

also pass a pointer to updateUser so if the user is modified inside
"validateUser" we can just return the modified user without do a new
query

old format too but you should upgrade to the new format to avoid future
issues
