Model.load(..) fails if called with deep=true

[GiacomoManzoli]

Hi,

i've noticed that Model.load doesn't call the callback if called with deep=true.
i.e.:

const client = new bimserverapi.BimServerClient(SERVER_ADDRESS);
// ...
client.getModel(
                poid,
                roid,
                schema,
                true, // deep
                loadedModel => {
                    console.log("Model loaded!");
                },
                "TestModel"
            );

this is due to the missing query param in the download call:

BIMserver-JavaScript-API/model.js

Lines 40 to 44 in fbe734c

	othis.bimServerApi.call("ServiceInterface", "download", {
	roids: [othis.roid],
	serializerOid: serializer.oid,
	sync: false
	}, function (topicId) {

This is also confirmed by the BIMServer, which logs

12:06:45 ERROR [qtp669700766-34]: Missing parameter: download -> query      

when the above code is executed
