So the problem is that when https://github.com/tute/merit/pull/146/files#diff-b36af4be06e39d478b3d39d216a368faR73 runs configuring eager_load_paths, `Merit.orm` is always the default `:active_record`. If I move that line to a later initializer, array is frozen and can't be modified (adding Mongoid models for instance).

Thinking how to solve it, if you have ideas, welcome!
