reversed execution order of the free callbacks in the previous commit

-onOpen now executes the callback associated with key None AFTER all
 sections have been opened and section-bound callbacks are executed
-onClose now executes the callback associated with key None BEFORE all
 sections have been closed and section-bound callbacks are executed
