stem cwd tests fail on macOS Sierra
I see the following stem tests fail:
test_cwd [FAILURE]
test_cwd_lsof [FAILURE]
======================================================================
FAIL: test_cwd
----------------------------------------------------------------------
Traceback (most recent call last):
File "/Users/twilsonb/tor/stem/test/integ/util/system.py", line 394, in test_cwd
self.assertEqual(tor_cwd, stem.util.system.cwd(runner_pid))
AssertionError: '/Users/twilsonb/tor/tor-master' != None
======================================================================
FAIL: test_cwd_lsof
----------------------------------------------------------------------
Traceback (most recent call last):
File "/Users/twilsonb/tor/stem/test/integ/util/system.py", line 447, in test_cwd_lsof
self.assertEqual(tor_cwd, stem.util.system.cwd(runner_pid))
AssertionError: '/Users/twilsonb/tor/tor-master' != None
----------------------------------------------------------------------
I wonder if it's because I am on macOS 10.12. Or something else about my environment. I used "STEM_SOURCE_DIR=../stem make test-full".
