Avoid test_connections_by_ss flakyness from IOErrors

Nick encountered another error from this test...

====================================================================== ERROR: test_connections_by_ss ---------------------------------------------------------------------- Traceback (most recent call last): File "/home/nickm/src/stem/test/integ/util/connection.py", line 50, in test_connections_by_ss self.check_resolver(Resolver.SS) File "/home/nickm/src/stem/test/require.py", line 58, in wrapped return func(self, *args, **kwargs) File "/home/nickm/src/stem/test/integ/util/connection.py", line 28, in check_resolver connections = get_connections(resolver, process_pid = runner.get_pid()) File "/home/nickm/src/stem/stem/util/connection.py", line 300, in get_connections raise IOError('No results found using: %s' % resolver_command) IOError: No results found using: ss -nptu

I'm unsure why this test is so flaky for him. Earlier I attempted to mitigate this by catching OSErrors but on reflection what he was really getting were IOErrors. Python *said* it was an OSError but that's because python3 has made IOError an alias...

In Stem 2.x I should probably replace IOError throughout our codebase with OSError. --- test/integ/util/connection.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
