Improve test coverage of using bulk actions when the view has an exposed form using AJAX

When I enable ajax in /admin/content view and try to perform a bulk action I see ajax command JSON on the UI.
Steps to recreate this issue.

1. Edit admin/content view and enable Use AJAX option.
2. Go to admin/content view and filter content by Content type.
3. Select all content by clicking on the checkbox
4. Select Publish content action from the select list and click "Apply to select items"

I expect this page to reload with the message "Publish content was applied to 50 items", but instead I see ajax command JSON output on the screen.
