Add lesson to class with remixed project

[loiswells97]

Status

Work in Progress: All the functionality should already be in place, but tests need adding as detailed below.

TODO

Add tests for the following:

• /lesson/remix request specs:
  • If teacher teaches the class and the original project is public, there is a 200 response
  • If successful, data is returned in the correct format
  • If the teacher does not teach the class, there is a Forbidden response
  • If the original project is not public, there is a Forbidden response
  • If the user is a student, there is a Forbidden response
• Remix project operation
  • When only the school_id is provided in the remix params, calling the operation increases the project count by 1
  • When only the school_id is provided in the remix params, calling the operation increases the component count by the number of components in the original project
    Note there is already a draft test for the above, but it's failing, so we need to figure out why
• Remix lesson operation
  • Creates lesson with the correct attributes (name, school, class, user etc.)
  • Remixes the original project and associates the remixed project with the new lesson
  • Errors as expected
