Nullify the default wallpaper component if it does not exist

The default wallpaper component cannot be found after GSI is flashed.
The home screen background will have no wallpaper and be black.
It will also cause the following CTS tests to fail:

- KeyguardTests#testDialogShowWhenLockedActivity
- KeyguardTests#testTranslucentShowWhenLockedActivity

The patch will check if the package of the default component exists.
If not, it will fall back to null, which is the AOSP default value, and
display the wallpaper in framework resource.
