Summary

When attempting to write a block similar to:

    ```text
    Some text to highlight in a text only code block
    ```

It causes a 500 error, but this worked fine in v5.2.

Steps to reproduce

1. Make sure you are using v5.3
2. Create or edit a wiki page
3. In the page attempt to utilise the "text" lexer (as shown in the summary above)
4. Try the view the page

Expected behaviour

For the wiki page to display with the code block highlight with no syntax highlighting as per the "text" lexer (e.g. the code blocks on this issue page is using the same lexer)
