Fix undefined array key "type" on empty array dump

[nicoorfi]

This PR fixes an edge case where the stream type is undefined when using the dump function, with an empty array.

For example

This works without problems

    public function foo()
    {
       // ...do something

        dump(['foo'=>'bar']);
    }

But this crashed the swoole server

    public function foo()
    {
       // ...do something

        dump([]);
    }

With the followring error:

   ErrorException 

  Undefined array key "type"
