Separates out the comment from the rest of the state return to make this
test more stable on Python 3. This state run in PY3 adds the minion
names to the comment in a random order, so we can't rely on asserting
against this order in the test.
This PR updates the test so that we are still checking for all of the
elements in the comment, but not relying on the order the minions are
added the comment list.
This ensures we do not introduce a regression which breaks
the usage of the `batch` option when using states in orchestration
runners.
