ApplicationHelper has already been included in ActionView::TestCase. Although some test classes inherit from ActionView::TestCase, they include ApplicationHelper in their own classes again. Therefore, we don't need to include ApplicationHelper in those classes because it is already included.

For example, the ancestry of WikiFormatting::MacrosTest is as follows, and it includes ApplicationHelper in the WikiFormatting::MacrosTest class again.

• WikiFormatting::MacrosTest < Redmine::HelperTest < ActionView::TestCase
