The Association Relation should use `empty?` and `size` from Relation.

968c581ea34b5236af14805e6a77913b1cb36238 have introduced this bug #14744
on Association Relation when the method `empty?` or `size` was called.

Example:
  # Given an author that does have 3 posts, but none of them with the
  # title 'Some Title'
  Author.last.posts.where(title: 'Some Title').size
  # => 3

It was occurring, because the Association Relation had implemented these
methods based on `@association`, this way giving wrong results.

To fix it, was necessary to remove the methods `empty?` and `size` from
Association Relation. It just have to use these methods from Relation.

Example:
  # Given an author that does have 3 posts, but none of them with the
  # title 'Some Title'
  Author.last.posts.where(title: 'Some Title').size
  # => 0
  # Now it will return the correct value.

Fixes #14744.
