Antonio Scandurra 32fbdfeab5 Avoid calling add_summary twice in sum_tree::Cursor ...

As I was looking into `SumTree` for the upcoming round of changes to the
buffer, I noticed that we were inadvertently adding summaries twice
every time we skipped over a node in the tree.

This is a pretty heavy code path that's pretty ubiquitous in the
codebase, so this commit gets rid of the unnecessary addition.
