Fix a typo that prevented UtilityCode.get_tree(entries_only=True) from working as expected. It looks like this doesn't make a difference for the generated C code (at least for the pickling, C++ STL and memoryview tests), but it should reduce the time it takes to collect the symtab entries defined in the tree.
