Fix query string to have null

[kobaska]

Fix to allow query string to have null. At the moment doing a find such as below would not work as qs.stringify function would remove the null from the query.

SomeModel.find({where: {name: null}});

Instead using JSON.stringify with encodeURI

Just a side note: In LB3.x we have worked on coercion and made both conversion and coercion more strict. null value is accepted only for "object", "array" and "any".
I see you sent this PR against 2.x. Could you please add test to verify the changes.
