test: give the 202-turn chat room test 30 seconds

The pinned message test makes 202 durable turns in order. It takes
about half a second on a laptop, but CI on the 1.0.3 merge commit took
5.6 seconds in the quality job, where 81 test files run in parallel
under coverage, and the default 5 second limit failed the run. Other
tests with this much durable work set their own limit.
