Problem description

Minimizing the app with "no background processes” settings on removes offline layers to add from the list and then trying to add layers crashes the app.

Steps to reproduce the problem

1. Set "no background processes" in the device.
2. Go to any form with maps and open the map.
3. Tap the offline layers icon, "add layers” and select some layers to add.
4. While on "Add layers” with the list of layer to add, minimize the app and go to a different app.
5. Go back to Collect (the list of layers to add is empty).
6. Tap "add layers”.

Expected behavior

I'm not sure what is the expected result - if it's possible to keep offline layers on the list in this case or it's better to close all the dialogs/bottom sheets

This happens because we store selected layers (layers to import) using LiveData and it gets cleared on process death. @seadowg do you think it's worth the effort to keep that data using SavedStateHandle? I was rather thinking about dismissing that confirmation dialog and letting users select the layers again.

I think for the moment we should just dismiss the dialog (going back to the picker) if this happens rather than investing in dealing with save state.
