Node#create with nil in one property doesn't create the node

[elado]

Neography::Node.create(x: nil, y: 1).neo_id # => nil

Neography::Node.create(x: 0, y: 1).neo_id # => "1"

Should reject nils from the hash if that's a problem.

data.reject { |k, v| v.nil? }

Anyway if there's an error it should be raised.

Update:

Looks like Neo4j server returns 500:

RestClient.post('http://localhost:7474/db/data/node/', {x:nil})

and HTTParty's post returns nil. I checked their docs and it should return a response object with .code. Any idea why?

In evaluate_response I log errors but return nil.
