MSC3030 Jump to date API endpoint

[MadLittleMods]

Add tests to ensure MSC3030 Jump to date functionality

MSC3030: matrix-org/matrix-spec-proposals#3030

Synapse implementation: matrix-org/synapse#9445

---

Includes nice debug statements when a test fails which give us the full history of messages in the room with color coding to show the expected and actual event alongside where the given timestamp fits into the list of events.

Todo

• Add sanity check test to make sure that you can't query for an event in a private room you're not invited to
