o Minor bugfixes (clietn, hidden service v3):
- Fix a BUG() assertion that occurs within a very small race window between
a client intro circuit opens and its descriptor that gets cleaned up from
the cache. The circuit is now closed which will trigger a re-fetch of the
descriptor and continue the HS connection. Fixes bug 28970; bugfix on
0.3.2.1-alpha.
