New functionality to update manually added links breaks links to other courses

The new functionality to replace the course ID (COURSEVIEWBYID*45) by the new course ID during a backup/restore, breaks manually added links to other courses.

For example I have a course with id=40.
On that course I have various resource links, some of them to the same course but others to a different course.
so http://.../course/view.php?id=45

After a backup/restore the new course will have ID=50
The problem now is that all resource links are altered by the new functionality and the links are now all pointing to http://..../course/view.php?id=50

I can understand that the links should be altered to ID=50 when the OLD ID is pointing to ID=40 but it should not alter the links to other courses.

Pls let me know your view on this, perhaps I'm missing something here...

If you agree this is a bug, I'm happy to share my workaround

Kind regards,
Jos
