## Issue Addressed

Closes #3612

## Proposed Changes

- Iterates through BNs until it finds a non-optimistic head.

A slight change in error behavior: 
- Previously: `spawn_contribution_tasks` did not return an error for a non-optimistic block head. It returned `Ok(())` logged a warning.
- Now: `spawn_contribution_tasks` returns an error if it cannot find a non-optimistic block head. The caller of `spawn_contribution_tasks` then logs the error as a critical error.
