Make sure tray widget doesn't move to other root windows.
There were two reasons why this was failing
- Test was using too small display (width=100), which
  makes the tray widget's origin outside of the root.
- GetDisplayNearestWindow was modified to use GetDisplayAt
 when we disabled extended desktop for 23. This fixes to use
 GetPrimaryDisplay()

I also added kStayInSameRootWindowKey to make sure it will
never leave the same root window.

BUG=none
TEST=ExtendedDesktopTest.OpenSystemTray pass without null check.
