Fix for lighthouse #6741
- adds tests for find_or_create_by and find_or_initialize_by on has_many associations
- changes the behavior of ActiveRecord::Associations::CollectionProxy#method_missing to differ to
ActiveRecord::FinderMethods#find_or_instantiator_by_attributes for arg processing and saving so
find_or_create_by's api on associations will be consistent w/ the api for model classes.
