Given the (DN, attrs) 2-tuple of an LDAP group, this returns the name of
the Django group. This may return None to indicate that a particular
LDAP group has no corresponding Django group.

The base implementation returns the value of the cn attribute, or
whichever attribute was given to __init__ in the name_attr
parameter.
