Handle saved password deletion when preference has been recreated

Handle saved password deletion when preference has been recreated

Previously, if the PreferenceFragment was recreated after returning
to the preference after attempting to delete a saved password,
the password list wouldn't be available and PasswordManagerPresenter
would fail to delete the password. Now, password deletion is handled
by PasswordEntryEditor, which always updates the password list
before attempting to delete.
