Potential null dereference in onRemove()

[angrytongan]

It's possible that parentNode is null, which causes a null dereference:

mapbox-gl-geocoder/lib/index.js

Line 395 in 5ac5826

this.container.parentNode.removeChild(this.container);

This can occur if the geocoder adds itself to a map, then map.remove() is called, and then the geocoder tries to remove itself from the map.
