Badge criteria "Completing a set of courses" allows to select courses that has completion tracking disabled

How to reproduce:

1. Make sure course completion is enabled on the site.
2. Create 3 courses with following completion tracking settings:
   1. Course 1 - completion tracking enabled
   2. Course 2 - completion tracking enabled
   3. Course 3 - completion tracking disabled
3. Go to site administration -> badges -> Manage badges and create a badge.
4. Then add a "completing a set of courses" criteria to that batch.
   1. The system should offer you the possibility of selecting course 1 or 2 but it also offers course 3 as a valid option.
5. Add course 3 to the completing course set
   1. The system must check the completion setting of that course before saving that preference.

The first bol issue is related to MDL-68315 but the second one must be solved apart.
