Added DatalabAPIError handling for create_item

[wuppersaver]

When creating an item while trying to attach it to a collection, which does not exist, the DatalabAPIError is not handled correctly. Adding this specific error to the except options solved the issue and correctly creates a collection to attach the item to.

Traceback:

resp = client.create_item(item_type=ITEM_TYPE_SAMPLE,item_data=payload, collection_id=collection_id)

Thanks for this @wuppersaver!

I'll make a minor tweak that makes the linters pass and then merge this.
