Fix spec failure in comment_spec.rb test_default_filter
Fix spec failure in comment_spec.rb test_default_filter

The test_default_filter method was checking the default filter:

  def test_default_filter
    a = Comment.find(:first)
    assert_equal 'markdown', a.default_text_filter.name
  end

But this was failing, because the underlying value was getting scrambled by
test_xss_rejection and not restored properly.  This patch fixes 1 unit test
failure, bringing the total to 12.
