Describe the bug

I'm using apidoc 0.24.0 for my project, and I generate my doc with 'aloneDisplay' set to 'true', but the footer is displayed in the header area in this situation, and I got an empty page when I click the footer link

Steps to reproduce

1. create a header.md and a footer.md
2. set header and footer to header.md and footer.md in apidoc.json
3. set template.aloneDisplay to true in apidoc.json
4. generate the doc, and you will see the footer is displayed in the header area

• Operating system (e.g. GNU+Linux/MacOS/Windows): Ubuntu
• Browser (e.g. firefox, chrome): Chrome
