Problem
Now that we've enabled use of the BB File picker in the LMS app it looks like we're running into similar or the same issue we had with the interaction between Canvas course copy and Canvas Files assignments. Namely that the launch URL when copied into a new course continues to reference a file in the old course.

Steps to reproduce

1. Create a BB Files assignment (e.g. "course copy test" in course MD Test course https://aunltd-test.blackboard.com/ultra/courses/_23_1/cl/outline)
2. Access as a student and confirm you can launch the file
3. As an admin, copy the course (Admin tools -> Courses -> select course -> "Copy")
4. Copy links and copies of the content (include entire course home folder)
5. Modify enrollments in the course so it has the same professor but a different student from the originating course
6. As a professor, enter the new course and make it available. Find the copied file and reset the permissions on it so students in the new course have access (permissions don't seem to copy over)
7. As a professor, try to access the copied assignment. See error message.
8. As a student, try to access the copied assignment. See error message.

In the above examples the old course file id was "file_id": "_10308_1", whereas the new course file if was "file_id": "_10725_1". Both the professor and the student received errors on the copied assignment. A new assignment using the copied file worked fine.

Expected behaviour

Ideally we would allow copied BB Files assignments to work correctly for professors and students in a new course without much work on the professor's part.
