Andras Bacsai 06b5a708b8 refactor(traffic): remove fallbacks for unreleased Sentinel builds
Every released Sentinel with traffic analytics (1.0.0 and later) has
the dashboard and series routes and the requests, bytes_in and app
fields, so the fallbacks for builds without them are not needed.

- Keep "no data" handling for Sentinel without traffic routes (0.0.x)
- Keep the resource-scope fallback, which Sentinel 1.0.1 needs
