map.querySourceFeatures on GeoJSON source throws TypeError if sourceLayer is missing

[noenandre]

mapbox-gl-js version: 0.37

According to the documentation parameters.sourceLayer is required on a vector tile source, an ignored on a geojson source.

However if you omits the sourceLayer parameter on a geojson source map.querySourceFeatures throws:
Uncaught TypeError: Cannot read property 'sourceLayer' of undefined

If i add a empty sourceLayer parameter like this:
map.querySourceFeatures("geojson_source_id", {sourceLayer: ''});
everything works as expected.
