Add clar helper to create new commit from index

There were a lot of places in the test code base that were creating
a commit from the index on the current branch.  This just adds a
helper to handle that case pretty easily.  There was only one test
where this change ended up tweaking the test data, so pretty easy
and mostly just a cleanup.
