v2/search breaks when pulling up a place with no observations_count

[OdileVidrine]

While updating a field that searches for places to use the v2/search endpoint, I came across this problem:
{ "status": "500", "errors": [ { "errorCode": "500", "message": "Invalid response for status code 200: results/0/place/observations_count: must be integer" } ] }
It seems that the observations_count field is null when there are no observations in that place, but the schema expects it to be 0.
