re-lax samesite cookie policy

Browse source 
As per discussion in code review:

> Cookies are always scoped in browsers. That's not the issue. SameSite attribute just protects against CSRF attacks. But Get requests (aka links) are also "protected" with Strict, which breaks it… and for users that is highly confusing when they (apparently arbitrarily) do not get the language they have set before when clicking a link.
