fix(security): Stop leaking urls on browser navigation

[dot-mike]

Regards linkwarden/linkwarden#1643 - [Browser Extension] Extension attempts to search every single visited website

This security-bug fix prevents the extension from leaking browser history to the self-hosted linkwarden instance. I'm sure the bug also affects the paid cloud instance of linkwarden, which makes this a serious violation of privacy for users.

I would also take the time to mention that browser extension is not mentioned in the privacy policy https://linkwarden.app/privacy-policy - which is linked from google extension page

before the fix, all URL navigation

19:22:12.472  200  /api/v1/search?sort=0&searchQueryString=url:https://news.ycombinator.com/
19:22:12.519  304  /api/v1/search?sort=0&searchQueryString=url:https://news.ycombinator.com/
19:22:12.546  304  /api/v1/search?sort=0&searchQueryString=url:https://news.ycombinator.com/

After the fix, only URLs I explicitly saved

19:40:24.682  200  /api/v1/search?...url:https://playaphone.com/
19:40:43.818  200  /api/v1/collections
19:40:45.603  200  /api/v1/search?...url:https://playaphone.com/
19:40:48.772  200  /api/v1/links
