[Android] Don't show sign-in promo when user is in SignedIn state

SignInPreference class shows the signin promo when there is no primary
syncing account present in chrome. Because the user can now be in
signed in state this can show sync promos and signin promos at the same
time.
SigninInPreference class should instead check for if there is signed in
account in chrome.
