    index: test for smudged entries on write only

Test that entries are only smudged when we write the index: the
entry smudging is to prevent us from updating an index in a way
that it would be impossible to tell that an item was racy.
Consider when we load an index:  any entries that have the same
(or newer) timestamp than the index itself are considered racy,
and are subject to further scrutiny.

If we *save* that index with the same entries that we loaded,
then the index would now have a newer timestamp than the entries,
and they would no longer be given that additional scrutiny, failing
our racy detection!  So test that we smudge those entries only on
writing the new index, but that we can detect them (in diff) without
having to write.

    • Write your modules and tests. Use good, meaningful names.

    • Make sure you actually build the tests by setting: 

        cmake -DBUILD_CLAR=ON build/

    • Test: 

        ./build/libgit2_clar

    • Make sure everything is fine.
