  [037]  test_run:cmd("stop server replica")

It happened because replication downstream status check occurred too
early, when it was only in 'stopped' state. To give the replication
status check routine ability to reach the needed 'follow' state, it
need to wait for it using test_run:wait_downstream() routine.

Closes #5293
