Non existing pages with a path with only two letters that is not a language code create parsing errors on the 'Page not found' page.

Describe the bug
Non existing pages with a path with only two letters that is not a language code create parsing errors on the 'Page not found' page.

E.g. 'https://docs.requarks.io/ab'.

It does not happen when you go to 'https://docs.requarks.io/en'. I imagine because this is a valid language code.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'https://docs.requarks.io/ab' or 'https://docs.requarks.io/cd' or 'https://docs.requarks.io/xy' etc.
   This also happens when you deploy wiki.js yourself.
2. See error

Expected behavior
Instead of notfound.* for docs.requarks.io or newpage.* in the case of the deployed wiki.js, it should show the correct content, e.g. This page does not exist yet..

Screenshots
If applicable, add screenshots to help explain your problem.

Host Info (please complete the following information):

• OS: Ubuntu 18.04, Docker
• Wiki.js version: 2.0.1
• Database engine: postgres 9.7
