Similar fix to #4533, but extending to some other clustered tests, as well as one super cluster test. Should prevent these tests from failing with `JetStream not enabled for account`. Signed-off-by: Maurice van Veen <github@mauricevanveen.com>
Could take some time for `o.processStreamSignal` to be called and up `o.npc`. Without would sometimes fail with `jetstream_test.go:24773: require int64 equal, but got: 0 != 1`. Signed-off-by: Maurice van Veen <github@mauricevanveen.com>
`TestJetStreamClusterRedeliverBackoffs` would sometimes fail, even though it would be very close to the intended backoff: ``` jetstream_cluster_2_test.go:4216: Timing is off for 1, expected ~100ms, but got 99.846642ms jetstream_cluster_2_test.go:4216: Timing is off for 0, expected ~25ms, but got 50.767748ms jetstream_cluster_2_test.go:4216: Timing is off for 4, expected ~250ms, but got 249.95211ms ``` Allowing for a bit of leeway on both ends.

…nge (#6332) Calling `require_NoError` in a `checkFor` immediately fails the test and doesn't allow for retries. Also up the max timeout when doing stepdowns, as that might sometimes take longer as well. Signed-off-by: Maurice van Veen <github@mauricevanveen.com>
Ack state could take some time to propagate, since the sent acks are not synchronous. Signed-off-by: Maurice van Veen <github@mauricevanveen.com>
Should solve this data race, where `rn.updateLeader(noLeader)` was
called without holding the lock.
