Steps

1. Click on button to navigate to any new screen
2. Navigate back
3. Click on button again to navigate to the same screen
4. Verify that nothing happens

This is probably due to StateFlow not handling the same data twice

Actual:

1. User open app
2. User press home/ multitask button
3. User returns to app
4. User press back
5. Verify that user can press back and still see the same screen

Root cause: because collectAsState is called multiple time, when the UI is recreated

Fix: Wrap it around LaunchedEffect and switch to SharedFlow, so the Flow is collected only once, but still passing duplicate values to UI, unlike SharedFlow (this is neccessary when user to a screen, go back and navigate to it again)

Stretch goals:

When token is already for sale, transfer token to another owner returns "You're not the owner of this token"
