Fix splitQueryPart()

[MashinaMashina]

Bug:
redirect()->to('/?param') returns url without param

If param has not value, it removes
/?param=1 => /?param=1
/?param => /

In php if you open page with ?param in $_GET array you will see this:
array (
[param] => '',
)

@lonnieezell why not just use parse_str() instead splitQueryPart()+decode()+other code in setQuery() ?

Honestly - because that function slipped my mind at the time and i was up to my eyes reading HTTP specs at the time :)

That's a perfectly good solution if you want to update to that.
