Loop inadvertently fails scheduling system when it has same system name.

This seems to only happen once in a while. Can be tested minimally on a build from test.project.json.

Error states that there's a cycle despite there not being any. Test case is in the Loop.spec.lua file on line 147.

The issue is most likely under the sort for unscheduled systems on line 218.
