* test(splash): the initial destination is navigated to once
* fix(splash): navigate to the first screen once
The splash screen asks for the initial destination on every onResume, which
runs again when the activity is recreated during startup while the view model
survives. The second navigation found the first already on the welcome screen,
with no route from there, and crashed the app with 'Unknown case for
welcomeFragment'. The view model now starts it once.
