Brendan Abolivier 84f7eaed16 Improve the UX of the login fallback when using SSO (#7152)
* Don't show the login forms if we're currently logging in with a
  password or a token.
* Submit directly the SSO login form, showing only a spinner to the
  user, in order to eliminate from the clunkiness of SSO through this
  fallback.
