Fix tracking of ancients

Browse Source 
We had been assuming that the `item` returned from batch.commit()
was the item committed, but it's actually the next item to be added
to the freezer, and multiple items can be committed in a single batch.

This commit finds the smallest item in the freezer and iterates from
that to the number returned by commit(), passing any tracked blocks
in that range to plugins.
