Joystick isConnected function not working properly

[luca-schlecker]

The Joystick isConnected function will only return false after attaching a controller if the program was started without a controller attached.
I think this functionality is lost during the DllImport. I've created a small C library which exports sf::Joystick::isConnected in combination with sf::Joystick::update. After I've used DllImport to import that library into C#, the functionality was also lost.
It works while writing the same program in C++.

Probably related to #189 and thus SFML/CSFML#136
