vw_model was switching back to exploration if there is no model data changes on server side since last update (i.e. if model export frequency is more than model downloader frequency).

I wonder whether we should avoid calling update in the first place if there was no refresh of data. Otherwise, every model that relies on refreshing data needs to implement this logic.

(Probably beyond the scope of a bugfix)

We changed how the model refresh logic works to stabilize the model update and avoid switching back to initial exploration (#56).

This change updates empty_data_transport to the new semantics and gets rid of the workaround in the unit test.
