REST API and PHP HTTPClient wrapper error: Invalid JSON body passed

[peterigz]

Since 4.7 I can no longer do a request with the php wrapper (​https://github.com/woocommerce/wc-api-php), so doing:

$order = $client->get('orders/'.$order_id);

I get the error "Error: Invalid JSON body passed". The body being passed is of course blank because there's no data needed for a get request. I guess the issue is in class-wp-rest-request::parse_json_params?

I can work around forcing a value in the data parameter in Client->Get but obviously not ideal :)
