Group describes with identical names in pretty printer

[Derpius]

Context

• The pretty printer displays describes with identical names as separate lists in the test report
  • This does not match the behaviour of Jest
• Grouping is useful as it allows for the describe.each({"case1", "case2"}), describe("case1") pattern to test common and distinct functionality for certain cases of (usually) an enum used to switch between logic in a commonised function

Scope

todo: scope this properly. Possible implementations given below for guidance

There are two possible implementations that would work here:

• Update only the pretty printer to group describes
  • This is my preferred approach
• Update the test runner to group describes
  • This is very edge-casey. We would need to see how jest handles e.g. lifecycle hooks defined in two different describes with the same name

Acceptance criteria

• The pretty printer displays tests and test suites from describe blocks with identical names grouped together
