[BUGFIX] Simulate usergroup in FE previews for restricted pages

This change also sets a "userGroups" record for a
simulated user group, and also the user, in order
to build a proper usergroup information, this way, the
FE preview also works for restricted pages, because
the userAspect is evaluated properly.
