local cache missing directories while running test suite

[jfindlay]

Description of Issue/Question

While running the test suite, I'm seeing a few of these for each test. It seems to be about one error per job:

...
11:05:53,273 [salt.loaded.int.returner.local_cache    :273 ][ERROR   ] Failed to write minion list ['minion'] to job cache file /private/tmp/salt-tests-tmpdir/syndic-master-root/cache/jobs/c0/66f130f1835df05186f585235b88a8/.minions.minion.p: [Errno 2] No such file or directory: '/private/tmp/salt-tests-tmpdir/syndic-master-root/cache/jobs/c0/66f130f1835df05186f585235b88a8/.minions.minion.p'

There doesn't seem to be any .minions.minion.p in any of these directories, but everything else in the path exists.

This appears to be fixed.
