Restoring a course backup does not restore the question bank with --overwrite option

[Badatos]

• moosh version: 1.14
• moodle version: 4.2.2
  • database: Postgres
• php version: 8.0
• operating system: Ubuntu 22.04.3 LTS

Actual behaviour

When we use MOOSH to restore a course backup with --overwrite option , it does not restore the question bank, it just delete all the questions.
nb: If we use the same command to restore the backup a 2nd time (or on a course with no question bank), it works well.

Expected behaviour

The course-restore --overwrite command must overwrite the question bank.

Steps to reproduce

1. Export a course backup with a question bank containing at least 2 questions
2. Modify the questions
3. Restore the backup with this command:
   course-restore --overwrite -e course.mbz [COURSE_ID]

For the record, I just tested the same manipulation directly inside Moodle (Restore the same course backup on the course already containing a question bank), and Moodle worked as expected. The problem really comes from Moosh.
