remove recursive relay discovery test

Recursive discovery relied on announcement events being gossiped across
relays regardless of whether they listed the service. Now that
announcements enter purgatory until state event and git data arrive,
cross-relay discovery cannot be triggered by a synced announcement alone,
making the three-relay recursive discovery scenario impossible.
