Optimize guard unwrapping expressions

[angelolloqui]

Kotlin allows ternary operators to return.

This code:

func showTenants() {
    guard let intent = coordinator.tenantsIntent() else {
        return
    }
    navigationManager.show(intent, animation: .push)
}

Translates to

fun showTenants() {
    val intent = coordinator.tenantsIntent()
    if (intent == null) {
        return
    }
    navigationManager.show(intent, animation = .push)
}

But could be

fun showTenants() {
    val intent = coordinator.tenantsIntent() ?: return
    navigationManager.show(intent, animation = .push)
}
