Fix GH-101 by removing fragile integration tests

The `tests in honcho/test/integration/test_ports.py` are fragile, as
they rely on processes starting up and echoing something before the
assert fires. They're using a `sleep 1` as a hack to try to make this
more likely, which surely is a sign of a bad test.
