Make 'repo' in strata sources lists default to name of chunk

In other words, consider the follow bit of stratum morphology:

    {
        "name": "foo",
        "kind": "stratum",
        "sources": {
            "bar": {
                "repo": "bar",
                "ref": "baserock"
            }
        }
    }

The "repo" field duplicates the name of the key in "sources". This is
unnecessary  now, so the "repo" field can be removed.
