fix: logged-in users with cookies set but database cleared to log out

Browse Source 
When switching databse data (for example restoring a backup etc.) and
a user is already logged-in (has a valid cookie, and thus PHP session)
but that user doesn't exist in the database anymore, we need to log them
out, since no data are available for them.
