Don't lose icons when migrating from different-sized hotseats.

Launcher2 on sw720dp devices had 8 hotseat slots; Launcher3
has only 6 on those same devices. When importing the old
hotseat, the empty slot (so technically there were 9)
occupied by the all apps button didn't line up with the new
all apps button, causing a hole on the hotseat. Furthermore,
the icon in old position 3 was clobbered by the new all apps
icon:

    0 1 2 3 (#) 4 5 6 7 ==> 0 1 2 (:) _ 4 5

In this CL we introduce a separate sort-and-place step for
hotseat icons so that any icon colliding with the new
all-apps slot can be moved to the right to find the next
nearest open slot. This works well for the 8->6 case; it
will probably do something reasonable, if not ideal, for
other grid migration scenarios.

But those are not covered by this bug.
