iotests: Make 245 faster and more reliable
Sometimes, 245 fails for me because some stream job has already finished while the test expects it to still be active. (With -c none, it fails basically every time.) The most reliable way to fix this is to simply set auto_finalize=false so the job will remain in the block graph as long as we need it. This allows us to drop the rate limiting, too, which makes the test faster. The only problem with this is that there is a single place that yields a different error message depending on whether the stream job is still copying data (so COR is enabled) or not (COR has been disabled, but the job still has the WRITE_UNCHANGED permission on the target node). We can easily address that by expecting either error message. Note that we do not need auto_finalize=false (or rate limiting) for the active commit job, because It never completes without an explicit block-job-complete anyway.
