SystemUI: fix some qs tile race conditions

Whenever setTiles() was called, we assumed all the tile animations had
finished, but if the eager beaver had grabbed a tile and dropped it on the
remove target before waiting for all the animations to complete, a lot of
assumptions are broken and crashes happen. Mainly because tiles aren't removed
from pages and we try to add them to a different page (like if they
needed to be placed a page back).

Implemented cancel for ongoing animations, which we call whenever
setTiles comes in. So all tiles should be in their proper state before
we try to cache/re-add them. Also cleaned up and documented setTiles().

Also, don't try to place the edit tile in the proper place, just add it
to the list if it's not present.
