Elijah Newren d13f7e9178 filter-repo: fix detection of merge becoming empty commit
In the previous commit, we detected when an entire line of history back to
a common ancestor of the merge became empty commits, and avoided having a
commit be merged with itself.  This commits looks through the changes
specified in the commit, which are always specified relative to the first
parent, so that if the first parent side was the empty one we can still
detect if the merge commit adds no extra changes relative to its remaining
parent.
