Windows user provider reports that the password is created instead of changed

If you change an existing user's password on Windows, puppet reports:

Notice: /Stage[main]/Main/User[testing6]/password: created password

If the desired password doesn't match current password, the windows_adsi provider's #password method returns :absent, to force the provider to apply the new password. But this causes puppet to think the property was "created".

It would be preferrable to say that the passwords were changed.
