BGE: Set render flag true on game start.

Fixes this bug:
1. add `logic.setRender(False)`
2. run game, exit game
3. remove the `logic.setRender` line
4. run game ... the render is still off

Now the render flag will be on by default on game start.

Note: during the game, the render flag stays unchanged across
game restart/load. It's only on initial game start that it is
initialized on.
