Don't use duplicate relations when eager-loading access list items and clients.

This fixes an Objection warning: 'Duplicate relation "proxy_hosts" in a relation expression. You should use "a.[b, c]" instead of "[a.b, a.c]". This will cause an error in objection 2.0'.

It also fixes the access list clients not being properly eager-loaded when building the proxy host nginx configuration files. Closes #434
