python: Don't try to bind a stat group to the NULL simobject.

That is a SimObject like object which is used when a SimObject
parameter is purposefully left empty, vs. being accidentally left
empty through a typo or accidental ommission.

It doesn't have a getCCObject method, and attempting to use it anyway
causes gem5 to crash.
