Adding quiet mode support for shortcuts

> LauncherApps returns empty list when the user is locked. Not relying on
LauncherApps in this case
> When the user is locked, removing all dynamic shortcuts
> Loading shortcuts from DB when the user is locked
> Verifying the shortcuts again when the user is available
