sim: Only consider non-NULL elements in SimObjectVector.has_parent.
NullSimObject doesn't have a has_parent function, and it's not clear what
its
return value should be if one were added. The appropriate value seems to
depend on why some other bit of code is checking if there's a parent in the
first place.
In SimObjectVector, the has_parent function is checking whether all of its
elements have a parent. In this particular case, the most reasonable thing
to do seems to be to just skip those elements.
