Fix duplicates work apps in launcher work folder after reboot

Cause:
When we run heuristic.processUserApps(apps), "apps" could be outdated,
as it's scheduled in mBindCompleteRunnables and only runs after bind
completed. The fix is get an updated app list and reschedule
processUserApps().

Test: Use DMAgent to activate work proifle, it does not show duplicated work
icons anymore.
