MDL-33971: When viewing course log entries for Quiz View Summary a number is displayed not the quiz name
MDL-43068 course&gradebook: show/hide cm & CONTROLS_GRADE_VISIBILITY

Making a quiz visible on the course page, of via the settings form,
could cause the grade item to become visible in the gradebook, even
though the quiz supports FEATURE_CONTROLS_GRADE_VISIBILITY to ensure
that when the grades are hidden in the quiz settings, they do not appear
in the gradebook.

Now, if a module supports FEATURE_CONTROLS_GRADE_VISIBILITY, then
set_coursemodule_visible calls the _grade_item_update callback to update
the grade item(s).

In addition, there was a bug when saving the quiz form, where it used
the value of $cm->visible from the database, which was wrong if the
value of cm->visible had just been changed on the setting form.
