[Android] add travel addon deeplink

A note about navigateUp and popBackStack here where we need to call a different function.
And about always emitting some Ui from the screen.
All good otherwise 😊

[StylianosGakis]

In the success case here we'd be emitting no UI at all.
Without knowing how this looks like, often this has led to animation glitches in navigation since we go from taking up 0x0 size to taking up the full size, and this size change is done with an animation by expanding the content from the center or top-left which is not what we want.

Can we either add an empty Box() in here, or even better wrap the entire when statement here in a Surface(color = ...background, modifier = Modifier.fillMaxSize()) { when(uiState)... } so that we always do emit at least the background properly?

[StylianosGakis]

Is this decided by now?

[StylianosGakis]

So from a button which normally takes you back one item in the backstack, but it is not the "up" arrow on the top-left of the screen, then what we must do is call this function here

android/app/app/src/main/kotlin/com/hedvig/android/app/navigation/RememberNavigator.kt

Lines 33 to 37 in 1f6e80c

	override fun popBackStack() {
	if (!navController.popBackStack()) {
	updatedFinishApp()
	}
	}

Easiest to pass down the popBackStack function from this navigator

android/app/app/src/main/kotlin/com/hedvig/android/app/navigation/HedvigNavHost.kt

Line 95 in 761a994

val navigator: Navigator = rememberNavigator(hedvigAppState.navController, finishApp)

down to this screen, and call that one on back from this button.
Since this screen does not seem to have a top app bar which we'd call navigateUp() from the top-left arrow, we probably just don't need to pass it down here at all in the first place.
