Title: Fix bugs with spatial reference and arcgis converters

There was a bug where is you try to convert from ArcGIS to GeoJSON with no spatial reference it would throw an error. This fixes that.

This also fixes converting spatial references on Features, FeatureCollections and GeometryCollections which used to throw a circular reference error. https://github.com/Esri/Terraformer/issues/74
