Preemptive circs should work with UseEntryGuards 0
Resume being willing to use preemptively-built circuits when UseEntryGuards is set to 0. We accidentally disabled this feature with that config setting (in our fix for #24469), leading to slower load times. Fixes bug 34303; bugfix on 0.3.3.2-alpha.
