In this test, we will monitor number of replication_changes_left to make sure replication is finished (replication_changes_left=0). In the runs with build 7.1.0-1831, we see the number of replication_changes_left becomes negative so the runs will never finish. The issue is reproducible.

We get replication_changes_left from the xdcr stats.
