The internal Mongo driver we use in our JS tests is not robust to primary failover.
In particular
new Mongo(replicaset_url)
Will throw in case the primary of the replica is stepping/shutting down.
Since we are passing a replica set URL the expectation is that the mongo driver is able to automatically switch to the new primary during initial connection.
Error example
Error: can't connect to new replica set primary [localhost:22005], err: Connection handshake failed. Is your mongod/mongos 3.4 or older? :: caused by :: network error while attempting to run command 'hello' on host 'localhost:22005' :: caused by :: dbclient error communicating with server localhost:22005 :: caused by :: futurize :: caused by :: Connection reset by peer

From the stack trace it looks like the problem is that as part of initial connection establishment we attempt to run a "whatsmyuri" admin command . This command is not being retried by the DBClientReplicaSet::runCommandWithTarget.
