Revert automatic cancellation of pending collection promises once the output promise resolves. This was introduced in 42d86b7 (PR #36, released in v2.3.0) and was both unintended and backward incompatible.

If you need automatic cancellation, you can use something like:

function allAndCancel(array $promises)
{
     return \React\Promise\all($promises)
         ->always(function() use ($promises) {
             foreach ($promises as $promise) {
                 if ($promise instanceof \React\Promise\CancellablePromiseInterface) {
                     $promise->cancel();
                 }
             }
        });
}

all() and map() functions now preserve the order of the array (#77).

Fix circular references when resolving a promise with itself (#71).
