bridge: remove all supervisor.SignalHealthy calls

Supervisor does not back off tasks that failed in a healthy state.

There are a couple places where we rely on supervisor for
application-level backoff, so we always want back-off. The distinction
is meant to enable runnables to implement their own specific back-off
logic, which we don't, so we can safely ignore it.

Fixes #37
