Steps to reproduce:

1. Create a new user and give them 'Course creator' role at one of the categories.
2. Log in as the new user and go to My courses page.
3. The user should see 'Create new course' link behind the 'No courses' text.

We are using core_course_category::user_top() to check whether the user has course management permission at any of the categories. At MDL-73549 a new get_nearest_editable_subcategory function has been created, and we should use it to decide whether to show or not to show the link to create new courses.

But the current behavior is that this is working when the user has permission at site level only.
