test(framework): remove stale relayNodes reflection in PeerManagerTest

PeerConnection.relayNodes was removed as an instance field (now a local
variable in a method). Calls to ReflectUtils.setFieldValue(p, "relayNodes",...)
caused findField to return null → makeAccessible(null) → NPE in every
test that used the pattern. Drop the dead setFieldValue calls and the
unused relayNodes field on the test class.
