CLONE - A teacher can add and remove topics

This is an exploratory test of a new feature or improvement, so please feel free to try anything you like and not just the test steps!

1. Create a topic format course with at least 7 sections and add some activities
2. Access the course as an editing teacher and turn editing on
   1. Check every topic has a "Add topic" link
3. Change the name of two consecutive sections
4. Click on "Add topic" link on the first renamed section
   1. Check a new section appears between both sections
5. Delete the created section (should be empty of activities as it is new)
   1. Check the section is deleted without asking for any confirmation (because it has no activities)
6. Rename a section that has no activities in it and delete
   1. Check a confirmation modal appears before deleting the topic (because it is renamed)
7. Delete a section that contains some activity
   1. Check a confirmation modal appears before deleting the topic (because it has activities)
8. Delete the first section
   1. Check the rest of the topics are renamed (if they don't have a custom name)
9. Confirm you can repeat all the previous steps to create and remove topics using keybord only.
