cosmetic updates for locate service changes

[kevinkreiser]

the output of locate now looks a bit different:

[
    {
        "input_lon": -1.783433,
        "node": null,
        "edges": [
            {
                "way_id": 24187895,
                "correlated_lat": 53.475826,
                "side_of_street": "left",
                "percent_along": 0.54,
                "correlated_lon": -1.783387
            },
            {
                "way_id": 24187895,
                "correlated_lat": 53.475826,
                "side_of_street": "right",
                "percent_along": 0.46,
                "correlated_lon": -1.783387
            }
        ],
        "input_lat": 53.475735
    }
]

instead of collapsing everything based on way_id we instead return all the graph edges, hence the only change for transitland is 'ways' -> 'edges'
