docs: Creates a slice of `array` excluding elements dropped from the end.
  Elements are dropped until `predicate` returns falsey. The predicate is
  invoked with three arguments: (value, index, array).

  @param {Array} array The array to query.
  @param {Function} [predicate=_.identity] The function invoked per iteration.
  @returns {Array} Returns the slice of `array`.
  @example
  
  var users = [
  { 'user': 'barney',  'active': true },
  { 'user': 'fred',    'active': false },
  { 'user': 'pebbles', 'active': false }

  // The `_.matches` iteratee shorthand.
  _.dropRightWhile(users, { 'user': 'pebbles', 'active': false });
  // => objects for ['barney', 'fred']
  
  // The `_.matchesProperty` iteratee shorthand.
  _.dropRightWhile(users, ['active', false]);
  // => objects for ['barney']
  
  // The `_.property` iteratee shorthand.
  _.dropRightWhile(users, 'active');
