Add HTTP basic auth headers to default filters

Technically only 'authorization' is used as a header, but PHP will
parse the username & password (or digest) — these aren't counted
as headers by PHP, but Symfony treats them as headers. Since a lot
of other projects use Symfony's HTTP foundation (e.g. Laravel), it
makes sense to add them as default filters too
