Display groupUUID on AccountGroupInfoScreen

It is possible to change the access rights for a project by directly
editing the 'project.config' file in the 'refs/meta/config' branch and
pushing the changes to Gerrit. If a project owner wants to assign a
privilege to a new group by editing the 'project.config' file, he also
needs to add the new group to the 'groups' file in the
'refs/meta/config' branch. To add the group to the 'groups' file the
UUID of the group must be known. Currently from the UI it is not
possible to find the UUID of a group. With this change the group UUID
is now displayed on the AccountGroupInfoScreen.
