Stop dispatching onFocus when debugger is not visible

[ACrazyTown]

This PR solves an issue where closing the debugger would dispatch an onFocus event.

One of the issues caused by this issue is sounds playing after the debugger gets closed.
If you play a sound, pause it, open the debugger and then close it, the sound will get unpaused and continue playing.

This code seems to have been added for a reason but I can't reproduce what the comment is saying. setting FlxG.stage.focus = null; doesn't seem to dispatch any focus events. Maybe its an old OpenFL version thing? Or target specific?

Can you clarify the repro steps? I need to play a sound, pause the sound, then press "~" twice and the sound will resume?

Yup! Play and pause the sound, open the debugger and close it. It'll dispatch a onFocus event which will then call this:

flixel/flixel/FlxGame.hx

Line 428 in 049e9ed

FlxG.sound.onFocus();

which will cause paused sounds to unpause and continue playing.
