 * component:  Tor => Stem


Comment:

 This is not a tor bug though the behavior is counter-intuitive (Changed
 the component, though I think Stem is doing the right thing as well).

 This is what is happening in the `launch_tor_with_config` call:
  1. Stem fork/execs a tor instance and waits for it to bootstrap to 100%.
  2. Tor starts up, and builds a test circuit to a random exit. (`Tor has
 successfully opened a circuit. Looks like client functionality is
 working.`)
  3. Tor finishes bootstrapping.
  4. Stem returns from the call.

 Since a usable circuit is already built (the one use for testing client
 functionality), tor is just attaching the incoming request to the existing
 (`BUILT`) circuit, and no circuit status events are fired.
