gnus-group.el: Check if group names are already strings

* lisp/gnus/gnus-group.el (gnus-group-group-name):
The group name may already be a string.
Specifically, in the group list reached from the *Server* buffer,
the 'gnus-group text property returns a string.  Everywhere else
it returns a symbol.
