MEDIUM: peers: unregister peers that were never started

The peers initialization sequence is a bit complex, they're attached
to stick-tables and initialized very early in the boot process. When
we fork, if some must not start, it's too late to find them. Instead,
simply add a guard in their respective tasks to stop them once they
want to start.
