Result for the current app not being kept if predictive back is cancelled by the user

[biennvops]

To reproduce:

• Open result from an app.
• Do a back navigation, but instead of going all the way, cancel it mid-way.
• The result will show as "NOT FOUND" and "UNKNOWN"

Expected behavior: Result from the previous app should still be there.

This is actually not simple to fix because the UI code depends on LaunchedEffect and data is passed around in a convoluted way.
