kirrg001 3b4edccf62 🐛 Fixed {{meta_description}} output when using data: page.{slug} in routes
refs #10599

- meta_description output wrong meta description

Only solves meta_description for this use case:

```
routes:
  /:
    data: page.{slug}
    template: t
```

/**
* # Response context
*
* Figures out which context we are currently serving. The biggest challenge with determining this
* is that the only way to determine whether or not we are a post, or a page, is with data after all the
* data for the template has been retrieved.
*
* Contexts are determined based on 3 pieces of information
* 1. res.locals.relativeUrl - which never includes the subdirectory
* 2. req.params.page - always has the page parameter, regardless of if the URL contains a keyword (RSS pages don't)
* 3. data - used for telling the difference between posts and pages
