Fix collection_from_options to allow Enumerators
An optimization was introduced in
https://github.com/rails/rails/commit/27f4ffd11a91b534fde9b484cb7c4e515ec0fe77
which tried to `#to_ary` the collection to prevent unnecessary queries
for ActiveRecord scopes/relations. If the given collection did not
respond to `#to_ary`, and empty collection was returned. That meant you
couldn't use collections built from `Enumerator` nor `Enumerable`.
With this change, `#collection_from_options` will attempt the
optimization, but fall back to passing along the given collection,
as-is.
