RasterLayer fails without URL

[duebbert]

I have a raster layer that I want to add without a TileJSON URL, so I'm loading it like this:

<MglRasterLayer
                :sourceId="layer.id"
                :layerId="layer.id"
                :minZoom="layer.zoom_min"
                :maxZoom="layer.zoom_max"
                :tiles="[layer.url]"
                :tileSize="256"
                :attribution="layer.attribution"
/>

This fails because mapbox-gl sees a url property on the source object. It's undefined but this seems to trigger a validation error in mapbox-gl and it ignores the tiles parameter then.

I believe the problem is in src/components/layer/RasterLayer.js line 47:

let source = {
        type: "raster",
        url: this.url,
        tileSize: this.tileSize
};

The url property should only be defined if this.url has been defined.

Must be fixed in 0.2. Feel free to reopen this issue if you still have this problem.
