Don't pass NA to geocoding API

[petrbouchal]

If passed NA, geocode() returns a whole lot of places containing "na". I suppose it should return the same value as when the geocoder cannot resolve the address.

This would be funny if it were not serious... Thank you, it will be corrected. Likely via a is.na() testing of input vector.
Thanks for raising the issue!

Well at least Namibia isn't involved gshs-ornl/wbstats#26

I heard good stories about Norway (ISO code "NO", evaluating as logical FALSE) in this context as well :)

v1.6.7 is on its way to CRAN - I had some issues with not-quite-graceful fail of unavailable internet resources & a brush with CRAN policy, so the timing was in a way fortunate
