Fixing backup restore

> Not deleting icons from cache, which have not been restored yet
> Not checking if activity exists during DB migration. Missing
components are removed during loader anyway
> Backing up and restoring bitmaps even when iconType is resource.
This allows us to show a proper bitmap icon, until the correct
resource is available.
> Loading proper shortcutResource icon for promiseIcons
> Checking against promise intent when verifying duplicates
> A launcher App intent can contain EXTRA_PROFILE
