Description:
------------
Any class that parses a URL will throw an exception when a URL with an empty query string (e.g. "http://www.example.com/?") is passed in.

Exception states: Failed to parse query; unexpected byte 0x00 at pos 0 in ''.

I tested http\Url and http\Env\Request.

At least one browser (Google Chrome) produces a URL with an empty query string when a form with no successful controls is submitted. Trying to create a new http\Env\Request object fails in these cases.


Test script:
---------------
new \http\Url("http://www.example.com/?");

Expected result:
----------------
(no output)

Actual result:
--------------
Fatal error: 
Uncaught exception 'http\Exception\BadUrlException' with message 'http\Url::__construct(): Failed to parse query; unexpected byte 0x00 at pos 0 in '''
