add test for Android runtime styling non-string type filters

[incanus]

#5979 was meant to fix filters of this sort:

LineLayer segments = mapboxMap.getLayerAs("segments");
segments.setFilter(eq("uniqid", new Integer(10191020)));
segments.setProperties(lineColor(Color.GREEN),
    lineWidth(10f),
    lineOpacity(0.5f));

However, it still doesn't seem to work (nor does eq("uniqid", 10191020)). Regardless, we should add a test scenario for a non-string type filter so that this one isn't the only thing being exercised (as well as fix the core issue, if it's really still happening).

@incanus See the example with numerical filters here: https://github.com/mapbox/mapbox-gl-native/blob/master/platform/android/MapboxGLAndroidSDKTestApp/src/main/java/com/mapbox/mapboxsdk/testapp/activity/style/GeoJsonClusteringActivity.java#L170

But I'll happily add another one.
