Back to search button stays active when opening a search page

We introduced the back to search button, so that we can go back to our original search after opening and/or editing a device/platform/configuration/site/contact.

However, when we don't use the button, but the navigation bar and open the search page there the button is still visible (but will only link to exactly that search page that opened right away).

So we should disable it, when we open the pages for the searches.
