Increase number of preemptive internal circuits

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.
