Fix update counters of multiple records with touch: true
Currently does not work the following example in the doc:
```ruby
# For the Posts with id of 10 and 15, increment the comment_count by 1
# and update the updated_at value for each counter.
Post.update_counters [10, 15], comment_count: 1, touch: true
# Executes the following SQL:
# UPDATE posts
# SET comment_count = COALESCE(comment_count, 0) + 1,
# `updated_at` = '2016-10-13T09:59:23-05:00'
# WHERE id IN (10, 15)
```
