fix(tests): more v2.0.0 API migrations (rng template, PeerId.random, etc.)

- tests/test_wakunode.nim: add std/options for Option.some disambiguation
- tests/test_peer_manager.nim: replace .withRng(rng) with .withRng(
  crypto.newRng()); PeerId.random() now takes Rng
- tests/test_waku_keepalive.nim: Ping.new now requires rng: Rng arg
- tests/test_waku_dnsdisc.nim: qualify ambiguous rng as common.rng()
