Filter out null island results

[stevage]

For whatever reason, Mapzen's geocoder is returning a lot of results whose geometry is [0,0]. Showing these results as autocomplete suggestions is pretty poor UX, and undermines user confidence in the geocoder.

For instance, typing "bl" gives this:

Apart from the 3 results from Switzerland, the other 7 results are all null island.

Hey @stevage, great catch! We missed a check for null island records in our openaddresses importer. Will add it shortly. Thanks for your feedback!

This has been fixed! 🎉 🎉 Thanks again for reporting the issue.

[stevage]

Awesome :) so it was fixed upstream, removing the need for a specific filter here?

@stevage, no we actually had a code change go through in a linked PR. No changes to the user interface of leaflet-geocoder or the API were made, however.
