PHPORM-266 Run tests on Atlas Local

Fix PHPORM-266

[jmikola]

Is this necessary to connect to the Atlas container? The subtle impact of this change means that you're going to establish a direct connection to the host instead of constructing a replica set connection. It'd be preferable to figure out what the appropriate replica set name is for each environment and fill that in here.

The Atlas Local container creates a replica set automatically, using the hostname of the container. But I can't connect using this replica set name.

Solution: skip the replica set configuration and use implicit direct connect for Atlas local.
