Update displayed owner group after group rename

In the AccountGroupScreen the group name and the
name of the owner group are displayed. A group
can own itself, in this case the group name and
the owner group name are the same. If now the
group got renamed by entering a new group name
and clicking on 'Rename Group' only the displayed
group name but not the displayed owner group name
was updated. With this change now also the
displayed owner group name gets updated on group
rename.
