Cannot distinguish local groups from global groups with the same name in the display of the page rights viewer

The page rights viewer displays the name of a group, without its scope (global or local).

Thus, for 2 groups that are called the same on main wiki and current subwiki, it's not possible to distinguish which rights are for the global group or the local group.

A good example is the default XWiki platform groups, XWikiAllGroup and XWikiAdminGroup, that are both present on main wiki and subwikis.

See the secreenshot on PRVA-8 for such an example of ambiguous display.

As a workaround, one can check the full URL of a group by hovering the link under the group name, and infer from the URL if it's a local or a global group.
