[TRAFODION-3243] Avoid dereference of deleted NAString in UPDATE STATISTICS
In the HSColGroupStruct destructor, move the call to
HSColGroupStruct::freeISMemory up to the front, before the "delete colNames"
statement. The freeISMemory method dereferences colNames. Before this fix, this
could cause cores.
