in lib/navigationlib.php in function load_activity()

the following call is made:
$gradingman = get_grading_manager($cm->context, $cm->modname);

in load_module_settings() the following call is made:
$gradingman = get_grading_manager($this->page->cm->context, $this->page->activityname);

All other uses of get_grading_manager (including the info in it's phpdoc) specifies that the frankenstyle name (mod_assign) should be passed instead.

I haven't seen an issue with the assign module but I'm working on adding support for advanced grading to the forum module and I noticed this variance.

We need to fix this to use the correct/consistent use of frankenstyle naming and check to make sure this doesn't cause issues with settings appearing in the navigation block
