Removed joint_permissions auto_increment id

Removed auto_incrementing id and set a primary key of the [role_id,
entity_type, entity_id, action] instead since this table could recieve a
lot of activity, especially when permission regeneration was automated,
leading to very high auto_increment counts which could max out the
integer limit.

Also updated some RolesTest comment endpoints to align with
recent route changes.

Should fix #2091
