Lingering reference to system_test_help function

OK that test fail suggests this might not be a novice issue. IIRC there is another issue for ignoring hooks from modules that are not installed. This might be a duplicate of that.

From the code context, it seems like the usage of that assert is to confirm system_test module is not installed. If there is an issue with checking hooks, then we can do the same assertion using module_handler's moduleExists function. Plz review the code.

Summary doesn't appear to match the MR. Should check the issue the assert was added to see what the goal was.

The assertion was added in #2160091-61: drupal_rebuild() rebuilds container twice, since drupal_flush_all_caches() also rebuilds it → (specifically comment #61). Have not reviewed closely, just identifying where it happened.

I guess since Hooks classes are now autoloaded unconditionally it doesn't make sense to check if a method exists. I've updated the test to check if the hook implementation exists instead.

Thanks for looking that up! Changes LGTM
