Extract path into variable
Update counter cache when pushing into association

This commit fixes a regression bug in which counter_cache columns
were not being updated correctly when newly created records were
being pushed into an assocation. EG:

    # this was fine
    @post.comment.create!

    # this was fine
    @comment = Comment.first
    @post.comments << @comment

    # this would not update counters
    @post.comments << Comment.create!

Make AM readme example more consistent

At 4a6eba32 mail sending example was rewrited from rails 2 format to
modern rails 3 approach. But passing parameter `recipient` to method
