Minor bug with findHit (document view)

[KCMertens]

There are two conflicting methods for hit navigation in the article view that can cause the current page in the document to change when the website is reloaded. (when the current url contains only findHit, findHit is removed and replaced by #hit-index e.g. #10. When refreshing, there are no longer wordstart/wordend parameter, and no findHit, the backend will serve the first page (with a hit?).

How it should work:

• The url as seen by javascript should always be the combination of wordstart/wordend/#hit-index
• The url in the back-end can be either findhit, or wordstart/wordend/#hit-index. It should be converted to the frontend format and redirect.
• The frontend paginator should just generate a new wordstart/wordend/#hit-index url.
