Activity events such as 'due' date events are not copied when selectively importing modules from another course that contain these events.

When restoring from a backup file or copying a course, events are successful copied to the new course.

Reproduction Steps:

1. Install vanilla Moodle
2. Create small test course
3. Edit assignment to add due date
4. Verify 'due' event created (in calendar or in DB)
5. Create new 'empty' course
6. On new course page, go to More > Course Reuse > Import
7. Select test course
8. Ensure 'Include calendar events' is selected
9. Jump to final step
10. Verify that due dates were not imported/copied to new course.

The new course assignments do contain due dates, however events for these due dates were not created
