Subject: proper error reporting for v3 onion services
APT connects just fine to any .onion address given, only if the connect
fails somehow it will perform checks on the sanity of which in this case
is checking the length as they are well defined and as the strings are
arbitrary a user typing them easily mistypes which apt should can be
slightly more helpful in figuring out by saying the onion hasn't the
required length.
