Fix the issue where shortcuts are removed in minimal device mode

When loading the workspace, Launcher pins/unpins shortcuts in comply
with the loaded workspace. Since minimal device mode creates a mostly
empty workspace, existing shortcuts are getting unpinned as a result.

To mitigate the issue this CL compares the db name and only invoke
sanitizeData when it matches the one defined in InvariantDeviceProfile.

1. add some deep shortcut in workspace (e.g. long tap on chrome, drag
"incognito tab" to workspace)
2. opt-in to sunshine fishfood (g/sunshine-teamfood)
3. enable bedtime mode with minimal device in Settings -> Digital
Wellbeing -> Show Your Data -> Bedtime mode -> Customize -> minimal
device
4. toggle bedtime mode, wait for apps in minimal device to show, then
toggle off bedtime mode
