Avoid idle WAL waits in checksum tests Switch to wait_for_replay_catchup in checksum tests to explicitly wait for the upstream flush LSN and not the write LSN. The write LSN can include unrelated unflushed WAL which isn't available for streaming on an idle primary.
In the test for using a rewound node as standby of a new primary in the 013_rewind suite; also switch WAL on the source before starting the target. This flushes through the minimum recovery point chosen to avoid a startup delay while an unflushed full_page_writes change waits for the background writer to log its next snapshot. This reduces test times significantly without changing the semantics of the tests.
