Revert "Merge pull request #7826 from sikachu/master-validators-kind"

This reverts commit 4e9f53f9736544f070e75e516c71137b7eb49a7a, reversing
changes made to 6b802cdb4f5b84e1bf49aaeb0e994b3be6028af9.

Revert "Don't use tap in this case."

This reverts commit 454d820bf0a18fe1db4c55b0145197d70fef1f82.

Reason: Is not a good idea to add options to this method since we can do
the same thing using method composition.

    Person.validators_on(:name).select { |v| v.kind == :presence }

Also it avoids to change the method again to add more options.

 ## Rails 4.0.0 (unreleased) ##
 
-*   `ActiveModel::Validators#validators_on` now accepts a `:kind` option which will filter out the
-    validators on a particular attribute based on its kind.
-
-        Person.validators_on(:name)
-        # => [#<ActiveModel::Validations::PresenceValidator:0x007fe604914e60 @attributes=[:name], @options={}>,
-        # #<ActiveModel::Validations::InclusionValidator:0x007fe603bb8780 @attributes=[:age], @options={:in=>0..99}>]
-
-        Person.validators_on(:name, kind: :presence)
-        # => [#<ActiveModel::Validations::PresenceValidator:0x007fe604914e60 @attributes=[:name], @options={}>]
-
 *   Add `ActiveModel::ForbiddenAttributesProtection`, a simple module to
     protect attributes from mass assignment when non-permitted attributes are passed.
