Browse Source 
## Issue Addressed

Closes https://github.com/sigp/lighthouse/issues/3085
Closes https://github.com/sigp/lighthouse/issues/2953

## Proposed Changes

Downgrade some of the warnings logged by the VC which were useful during development of the sync committee service but are creating trouble now that we avoid populating the `sync_duties` map with 0 active validators.
