Guillaume Bertholon f3a180bc09 Fix sf::Context::getActiveContext to stop returning inactive contexts
sf::Context::getActiveContext could return an inactive context if
RenderTargets activation occured since the last sf::Context activation.
This is not what its documentation suggest, and was clearly an
unexpected behaviour.

This fix make the function return NULL if the current active context is
not managed by sf::Context (e.g. because it is a RenderTarget).
