[Launcher] Weird bounce back effect when organising items

[Vesa Rautiainen]

Steps to repro:

1) Long press an item in the Launcher (Quicklist appear)
2) While long pressing start moving the item (drag&drop mode entered). Item detaches from its previous place
3) Drop the item at the top of the icon column to be the topmost.

Expected behaviour:
Item animates nice in to its place without any additional movement.

Actual behaviour:
Item animates in to its place ok but also whole column of items moves downwards and bounces back.

Desired solution:
Expected behaviour above
