Fix test race between primary XLOG_RUNNING_XACTS and standby logical slot.
Before the previous commit, the test could hang until
LOG_SNAPSHOT_INTERVAL_MS (15s), until checkpoint_timeout (300s), or
indefinitely. An indefinite hang was awfully improbable. It entailed
the test reaching checkpoint_timeout before the
DecodingContextFindStartpoint() of a CREATE SUBSCRIPTION, yet after the
preceding WAL record. Back-patch to v16, which introduced the test.
