Exception raised when getting related nodes (and receiver node has no relationships)

[CountCulture]

I've only just started playing around with Neography (and Neo4J), so not sure if this expected behaviour, but if I do the following:

node = Neography::Node.create("age" => 31, "name" => "Max")
node.both.size #or any array-type functions

I get

NoMethodError: undefined method `collect' for nil:NilClass

This appears to be caused by this line:

return nil if node_relationships.empty?

which is expected to be something that responds to collect.

Happy to do a spec/patch/pull request if this is a bug rather than expected behaviour

Seems to me that this is a bug. Would you agree, @maxdemarzi ?
