This test fails when the node targeted for the $merge is a v4.2 node, because making a shard node refresh on returning StaleDbVersion was added in v4.4. As a result, the node sending the $merge to the v4.2 keeps getting StaleDbVersion and keeps retrying until it runs out of retries, causing the test to fail.
