[PATCH 1/3] cherry-pick: add test for `--skip` advice in `git commit`

[Johannes Schindelin via GitGitGadget]

From: Johannes Schindelin <johannes.schinde...@gmx.de>

In dcb500dc16c (cherry-pick/revert: advise using --skip, 2019-07-02),
`git commit` learned to suggest to run `git cherry-pick --skip` when
trying to cherry-pick an empty patch, but that was never tested for.

Here is a test that verifies that a message is given to the user that
contains the correct invocation.
