Allow users to unlike an already liked content

I have attached a patch to update the vote. Please review it.

Thanks you all for working on this issue.

Done some major fixes around like & dislikes within 2.2.0 → release,
Have a check if this issue still exist with 2.2.0 → version?

Tested on 2.x & 2.2.0.
Now the functionality is working as describe below:
1) If an authenticated user likes an content type, and again by pressing the like button a msg is shown: " You have already liked..! ", and for dislike button also same behavior is seen with a msg "You have already disliked..!".
2) If an authenticated user likes an content type, And then dislikes it the like count reduces to 1 and dislike count increase by 1. The same behavior is seen for dislike button.

Added screenshot for UI reference.
