With these options (the default in TypeDB at time of writing), the server may respond with: 50 answers -> CONTINUE -> 1 answer [compensating for latency] -> DONE. The client will respond to CONTINUE with STREAM to keep iterating, and the server responds to STREAM with a 2nd DONE message.
This is expected and should be handled correctly (ie: ignored) by the client.

do we still need the bidirectional stream in this class at all?

What is the goal of this PR?
We no longer delete response collectors in a transaction after receiving a response to a "single" request, or receiving a "DONE" message in a stream. This fixes a possible error when loading 50+ answers in one query and then performing a second query.
