 Stem's integration tests are run by e.g. `run_tests.py --all` or `tox`,
 and by default do not include the `ONLINE` target. (See `run_tests.py
 --help` for more info on running `ONLINE` tests.)

 These remaining integration tests should be runnable offline; however, it
 appears that they require the `tor` process to bootstrap to 5% in order to
 run.
 Waiting for 5% was introduced in commit
 `fbfa73a099d9645f18d9846420cbf0145065b11d` from 2011.

 Empirically, I switched this to 0% and all these integ tests still worked
 fine.

 In chatting with atagar over IRC, he wasn't aware of a reason offhand for
 waiting for 5%, and suggested we could change this since the tests still
 pass.
