Android: fix call of glFinish without context.

Browse Source 
Message in the log, when going to background:
"call to OpenGL ES API with no current context (logged once per thread)"

Because of SDL_WINDOWEVENT_MINIMIZED is sent from the Java Activity thread.
It calls SDL_RendererEventWatch(), _WindowEvent() and glFinish() without context.

Solution is to move sending of SDL_WINDOWEVENT_MINIMIZED to the SDL thread.
