o Minor bugfixes (v2 single onion services):
- Always retry v2 single onion service intro and rend circuits with a
3-hop path. Previously, v2 single onion services used a 3-hop path
when rend circuits were retried after a remote or delayed failure,
but a 1-hop path for immediate retries. Fixes bug 23818;
bugfix on 0.2.9.3-alpha.
