Found that test replication/skip_conflict_row.test.lua fails with
output message in results file:

Test could not be restarted with checksum because of changing values
like UUID on each fail. It happend because test-run uses internal
chain of functions wait_upstream() -> gen_box_info_replication_cond()
which returns instance information on its fails. To avoid of it this
output was redirected to log file instead of results file.
