Empty Categories in My Courses are always shown.

Create these categories and courses: cat1, with course c1 cat2, with course c2 cat3, without courses and with subcategories: cat31, with course c31 cat32, with course c32 cat33, with courses c331 and c332 Enrol a user (as student) in all the "odd" courses (those which name ends with "1", aka c1, c31 and c331). Log in as that user. In the navigation block, my courses: With $CFG->navshowmycoursecategories disabled you get the raw list of courses in the block (c1, c31 and c331). With $CFG->navshowmycoursecategories enabled, expand the whole tree, you get the categories tree and only the enrolled courses (c1, c31 and c331). Both the category cat2 and and cat32 aren't shown in the tree as far as the user does not have enrolled courses there (before the patch c32 was shown in the tree). Optionally, if MDL-40392 is already integrated, run the behat tests specified there, they should pass (2 scenarios).
