Show hint if password is empty during login

A user might have an empty password due to two reasons:

* The user just created an account and needs to set an initial password.
* The password has been reset by the administrator.

In both cases, the user might be confused as to why the login does not
work. Add a message that helps users debug the issue in both cases.
