refactor!: remove isStarted method from Startable (libp2p#2145)

We have an `isStarted` method on the `Startable` interface but we only
really use it in tests. Our implementations tend to guard on being
started twice so it just adds noise to every implementation.

BREAKING CHANGE: the `isStarted` method has been removed from the `Startable` interface
