Removed FIXME

Asterix, this method is actually new (i.e., was only in gc before),
but now it is needed (see #1495).  Also, what I was not expecting
was the refresh of self.contact in this same function.  This is
required since the contact goes stale when we go offline.
Not sure if that is a bug or not.
