Halo: Icon reorder in Phone/Tablet status bar (fix repositioning after flips)

When tearing down notification panel halo is near quick settings button (no notifications present). When you flip to QS panel and then reflip to notification panel Halo icon change position, moves to third icon layout (as when clear-al button is there) from right instead to stay in the second one.
Icons layouts are reordered and fix this behaviour. From left to right:

Clear-All button // Halo button // QS button.

-ToDo: When tearing up the Tablet status bar Clear-All button shows for a moment if no notifications are available, but only the first time. A minor issue, will be fixed as soon as we can.
