Merge pull request #9308 from joernchen/patch-1

Update activemodel/CHANGELOG.md
Fix handling of dirty time zone aware attributes

Previously, when `time_zone_aware_attributes` were enabled, after
changing a datetime or timestamp attribute and then changing it back
to the original value, `changed_attributes` still tracked the
attribute as changed. This caused `[attribute]_changed?` and
`changed?` methods to return true incorrectly.

Example:

    in_time_zone 'Paris' do
      order = Order.new
      original_time = Time.local(2012, 10, 10)
      order.shipped_at = original_time
      order.save
      order.changed? # => false

      # changing value
      order.shipped_at = Time.local(2013, 1, 1)
      order.changed? # => true

      # reverting to original value
      order.shipped_at = original_time
      order.changed? # => false, used to return true
    end

don't cache invalid subsets when preloading hmt associations.

Backport #9252.

The preloader code on 3-2-stable is not based on relations but on option hashes.
I had to modify the original patch and comparing the option hashes could be more
fuzzy than comparing the relations. All the tests passed though.
Merge pull request #9322 from senny/backport_9252

don't cache invalid subsets when preloading hmt associations.
keep the build :green_heart:, #first on 1.8.7 and pg is different

The build only failed for ruby-1.8.7 and pg. The problem was that the statement:

```ruby
author = Author.includes(:comments_with_order_and_conditions, :posts).first
```

resulted in Author with ID 2 where on all other rubies / db-engines Author with ID 1
was retunred. Of course this breaks the assertions.

desired order
