refactor(UserAPIController): Extract RunInfoController

[Aaron-Detre]

Changes

• Moved methods and tests relating to "run info" from the Student and User API controllers into its own RunInfoAPIController class.

Test

• For this to work, you'll also need this client PR: Updated URLs for RunInfoAPIController refactor WISE-Client#2132
• To test the endpoint at api/run-info/run/info, go to 'Student Home,' click 'Add Unit,' and enter some text that isn't a valid access code. Click off to the side, and it should say "Invalid Access Code."
  • Then enter a valid access code, and the warning should go away.
• To test the endpoint at api/run-info/run/info-by-id, go to 'Student Home' and click 'Report Problem' on any unit. The contact form should include a line showing the name of the project that you clicked on.
• Make sure moved tests still pass.

Closes #292
