Show password dialog when setting Call Barring without UT

Password dialog might be missing when setting Calling Barring when UT is
disabled. This will cause the Call Barring request to fail since
password dialog should always be shown when setting Calling Barring
without UT.

Correct by changing logic to verify that password dialog is shown if
UT is disabled.
