Creates a slice of `array` with elements taken from the end. Elements are
taken until `predicate` returns falsey. The predicate is bound to `thisArg`
and invoked with three arguments; (value, index, array).

If a property name is provided for `predicate` the created "_.pluck" style
callback returns the property value of the given element.

If an object is provided for `predicate` the created "_.where" style callback
returns `true` for elements that have the properties of the given object,
else `false`.

@example

_.takeRightWhile([1, 2, 3], function(n) { return n > 1; });
// => [2, 3]

var users = [
  { 'user': 'barney',  'status': 'busy', 'active': false },

  { 'user': 'pebbles', 'status': 'away', 'active': true }
];

// using "_.pluck" callback shorthand
_.pluck(_.takeRightWhile(users, 'active'), 'user');
// => ['fred', 'pebbles']

// using "_.where" callback shorthand
_.pluck(_.takeRightWhile(users, { 'status': 'away' }), 'user');
// => ['pebbles']
