[Tarantool-patches] [PATCH v1] test: flaky replication/gh-4928-tx-boundaries test

["Alexander V. Tikhonov" <avtikhon@tarantool.org>]

On heavy loaded hosts found the following issue:

It happened because replication upstream status check occurred too
early, when it was only in 'disconnected' 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_upstream() routine.

Closes #5234
