[Default launcher] Issue with loadWidgets()

Hello!
I'm trying to add a fullscreen mode to the default Launcher. The code is in this branch and it works. I'll send a PR to upstream later.

I noticed that other fullscreen apps load the widgets overriding the draw method using this code:

for (let wd of WIDGETS) {
	wd.draw = () => {};
	wd.area = ""; 
}

I like the idea so I updated the code:

Bangle.loadWidgets();

if (settings.fullscreen) {
	for (let wd of WIDGETS) {
		wd.draw = () => {};
		wd.area = ""; 
	}
} else {
	Bangle.drawWidgets();
}

I did some tests: the fullscreen mode works but I don't receive the notifications. The same approach works in other apps (like the Pebble Clock).

Am I missing something?

Thank you :-)
