dev-python/automat: Fix test failures for bug 665554

automat _visualize.py code depends on both twisted and graphiz modules.
This patch fixes the condition where some tests were not skipped due
to twisted not being installed, but graphviz was.

+Subject: [PATCH] Fix _test_visualize.py twisted import errors
+
+When graphviz modules are installed but not twisted, this creates test failures
+in _discover.py which hard depends on twisted being installed.
