Fairly often, evergreen tasks will fail with a server selection error, like this:

[2020/03/09 10:50:52.818]   No suitable servers found (`serverSelectionTryOnce` set): [connection refused
[2020/03/09 10:50:52.818]   calling ismaster on 'localhost:27017']: generic server error 

When the task is restarted, it will usually succeed on a subsequent run.  We should improve these tests to be less flaky.
