    Increase number of preemptive internal circuits
    
    When we connect to a hidden service as a client we may need three internal
    circuits, one for the descriptor retrieval, introduction, and rendezvous.
    Let's try to make sure we have them. Closes #13239.

+  o Minor bugfixes (hidden service client):
+    - Increase the minimum number of internal circuits we preemptively build
+      from 2 to 3 so they are available when a client connects to another
+      onion service. Fixes bug 13239; bugfix on tor-0.1.0.1-rc~460.
