Correctly handle multiple attribute method prefix/suffixes which match

Active Record defines `attribute_method_suffix :?`. That suffix will
match any predicate method when the lookup occurs in Active Model. This
will make it incorrectly decide that `id_changed?` should not exist,
because it attempts to determine if the attribute `id_changed` is
present, rather than `id` with the `_changed?` suffix. Instead, we will
look for any correct match.
