[System Test][XDCR] goxdcr keeps crashing with panic in FetchLatestReplicationsInfo

I started two longevity runs on nov 5, one with weekly build 7.1.0-1650 and other with 7.1.0-1653 that has the debug messages for MB-48884 - goxdcr constantly keeps crashing in both with the following panic:

Service 'goxdcr' exited with status 2. Restarting. Messages:
