Make protected tags spec the same for CE and EE
Make protected tags spec the same for CE and EE

This changes a protected tags feature spec so that it is the same in
both CE and EE. This requires the use of a `if Gitlab.ee?` check, as the
added lines don't work in CE but do work in EE. Removing them entirely
in turn breaks the EE spec.
