Frameworks: make recent multiuser compatible

wondering how it worked at all on AOSP recents. Whatever call the
list dependent on the user who is using it

Change-Id: Ieae1d8ee2b71597bcb2025222c22d4514220ecc3
Frameworks: derp

well it does not effect us due that we proper preload etc. But if it is not
a cancel repload event should reset the mIsPreloaded flag

sorry
