While testing MDLQA-15306 I have noticed when I try to navigate away from the self enrolment form and I didn't get the form change checker:

1. Create a new course
2. View the list of enrolment methods
3. Enable the self-enrolment instance
4. Edit the self-enrolment instance
5. Attempt to navigate away without saving changes
   1. Confirm no form change check
6. Click to set an enrolment key
7. Attempt to navigate away without saving changes
   1. Confirm form change checker doesn't came up
