amend: add tests for amending only some files from commit to be amended

We do not have robust enough tests for scenarios where only some files in a
changeset are amended. This presents an interesting scenario because the
working copy could have modified versions of the remaining files in the
pre-amend changeset. Therefore, I have added some tests to ensure that amend
behaves as expected in these scenarios.

Test Plan:
Ensured that the test "test-commit-amend.t" passes.
