GeoJson type inference can fail if there are fields without any values in the sample

If there are props that don't have any valid values in the sample, the type inference will return an empty seq, and the call to .head will fail.
We could either ignore those fields, or assume strings.
For example: `{ "properties" :

{ "foo" : "" }

}` will fail to infer anything.
