    user-accounts: Correctly hide password mismatch warnings
    
    The logic for the password mismatch warnings didn't handle the case where
    you deleted both the passwords - it would still show them as not
    matching.
    
    Fix this by handling the three cases:
    - Passwords are different
    - Passwords are the same
    - No passwords entered
