rewriteutil: handle dropped commits when updating description hashes

In looking to leverage this with the absorb extension, the old -> new mapping
there allows the new value to be None.  We could filter that out and not pass it
to this method, but it seems worth a message to the user.  (I wonder if these
should be an info or warning, because it's unlikely people are using `-v`
regularly.)
