localrepo: don't use raw context when checking for an empty commit

This switches one of the cases in the if statement checking for empty
commits to use the commitable context instead of the raw working
context.  The point of this change is that there is now a clear
distinction between the part of localrepo.commit() where we are
operating on the raw context and the part where we are operating on
the commitable context.  This is turn will make it proactical for
future patches to split up the function.

This is part of a larger refactoring effort to make memctx more
useful, and make it easier to smoothly commit in memory.
