Updates the default member type property types to use "Labels", then needed to update the member type repo and membertypereadonlyfactory to ensure that even though the underlying data type for the property exposes a different Db Type that we 'reset' that Db Type to what it always should be. This means that no matter what underlying data type a developer changes a property to, if it is a built-in membership property, the Db Type will always stay consistent and save in the correct column. Of course if someone enters some invalid data, then the data will not be saved.
