Force the adapter to rebind cards with a toggle.

A card dismissal and scheduled card collection trigger a reload. During
card reloading, we perform slices pre check. The pre check goes through
the whole slice binding process, which means slices will be pinned and unpinned.
Hence, the on screen slices will gets unpinned resulting to the
unresponsive toggling.

As we have DiffCallbck implmented, if the card list are the same, then
bindView in the renderer will be ignored, which means the unpinned slice
will have no chance to re-register slice callback. So here we force it
to rebind the views.
