This commit fixes 2 issues, both coming from a misbehavior in
`get_nearest_lang()`:
1. Anyone could reach the website in a lang available in backend but not in
frontend. Eg, french is activated but not a website lang, going to `/fr`
would show the page in french.
2. As a logged in user coming from backend in a lang not available in frontend
(has request.lang set to that lang), the website would show a 500 error page
since it would not filter out the current request lang.
Both these issues are fixed here by ensuring langs are filtered out if they do
not belong to the frontend (website langs).
Step to reproduce (bug 1):
- Install french in backend lang (not on website)
- Visit `127.0.0.X/fr_FR`, the frontend will be displayed in french even if
it not a lang available in frontend.
Step to reproduce (bug 2):
- Install french on frontend and remove english from frontend
- Navigate to the backend /web
- Navigate to frontend, it will crash
