trebuchet: ensure not overlaping shorcuts and drop items when searchbar is invisible

If searchbar is hidden (via settings) in portrait mode in no tablets devices, the first row
of shortcuts overlaps the drop target view, which made impossible to positioning the
drag shorcut in the same cell because is ocuppied by the remove drop target.
This change, in the conditions described previously, animates the workspace to
ensure the drop search bar has enough space without overlapping the workspace layout.

Also give an extra padding (edgeMarginPx) to the workspace when searchbar is present.
Actually, the search bar and the first row of shortcut icons are too much closed.
