Apply workaround fix for replication checkpoints test against R14B01

R14B01 and R14B02 both are affected to OTP-9167 Erlang issue which
causes 4 tests failure because supervisor restarts worker with old
ChildSpec ignoring changes in use_checkpoint options.

This fix makes all tests passed, but leaves a notice in verbose mode
that there is a problem and how it could be resolved.

Another possible solution is to isolate test_use_checkpoints calls, but
this will be only hide the issue while it still may happened in prod.
