need to call Vfs\StreamWrapper::init_static() after setting Vfs::$user

Browse Source 
Vfs::$user should be protected and moved to Vfs\Base plus a getter and setter method added for public access,
as after setting it in 21.1+, Api\Vfs\StreamWrapper::init_static() need to be called to set the default user context!
