Create new qualifying test report

[warrensearle]

As an admin
I want to create a qualifying test report
So that I can analyse scores across one or more tests

---

Form to allow the creation (and editing) of a qualifying test report.

The form will allow the selection of one of more qualifying tests for the current exercise. The tests should be 'complete' and should not be 'mop up' tests.

A query like the following will cover this:

.where('status', '==', 'completed')
.where('mode', '!=', 'mop-up')

Data model for qualifyingTestReport

exercise: {
  id: String,
},
qualifyingTests: [
  { 
    id: String,
    title: String,
    maxScore: Number,
  },
],

This relies on digital-platform#419 so cannot be tested yet. Have moved to 'blocked' whilst we complete that work.

This is now complete.
