This method is like `_.findIndex` except that it iterates over elements
of `collection` from right to left.

@param {Array} array The array to search.
@param {Array|Function|Object|string} [predicate=_.identity]
 The function invoked per iteration.
@returns {number} Returns the index of the found element, else `-1`.
@example

var users = [
  { 'user': 'barney',  'active': true },
  { 'user': 'fred',    'active': false },
  { 'user': 'pebbles', 'active': false }
];

_.findLastIndex(users, function(o) { return o.user == 'pebbles'; });
// => 2

// The `_.matches` iteratee shorthand.
_.findLastIndex(users, { 'user': 'barney', 'active': true });
// => 0

// The `_.matchesProperty` iteratee shorthand.
_.findLastIndex(users, ['active', false]);
// => 2

// The `_.property` iteratee shorthand.
_.findLastIndex(users, 'active');
// => 0
