I don't think we need `swipeIntentionRouter` and `swipeOptions` do be declared on `CallScreen`, we should create a separate method, `initLockScreenSlide` maybe, doing the init and having the options as simple vars inside it.

Looks like we're also not using the `this.swipeHanlder` reference.

Then we should call this method (`initLockScreenSlide`) only when we're in locked mode.

BONUS: this method should be easily testable :)
The basics, testing that we're instantiating a lockscreenslide/showing the clock etc...
And testing that the method is called only when we're locked.
