MongoDB tests not working correctly

    Details

      Description

      There are two issues with MongoDB tests

      FieldBlacklistIT and FieldRenamesIT are failing on MongoDB < 3.6. The reason is that the assertion expects "$v": 1" in incoming messages but this is not present in older versions. Example starcktrace is

      org.junit.ComparisonFailure: expected:<'{"$[v": 1,"$]set": {"phone": {"$n...> but was:<'{"$[]set": {"phone": {"$n...>

      The other problem is that MongoDbConnectorIT.shouldConsumeAllEventsFromDatabaseWithSkippedOperations() is unstable. Depending on the timing the test fails with
