Adjust Ensemble sensor GET to handle missing paramter_types

[kathyavini]

Description

This is not a full-fledged solution for the problem of the Ensemble API maybe being in flux, this is just restoring our Sensor List for now.

paramter_types is no longer returned from the device endpoint. Actually I don't think the info has been replaced yet -- I see a property paramaters but it is null. Maybe parameter_types will be restored? I'm not sure.

As of yet I don't think the frontend uses it so it may be safe to remove entirely in the future when we revisit the Ensemble device endpoint closer to release.

There are Sentry errors and everything for this :) Based on the timing I guess the Ensemble API was changed yesterday.
