[PATCH 1/2] t3507: pin CHERRY_PICK_HEAD absence for a conflicting --no-commit

The tests here check the ref after a conflicting pick, after a clean
pick and after a clean pick under --no-commit, but not after a
conflicting one under --no-commit.  That is the combination a user
runs into by accident: the pick stops with conflicts, and the ref
"git commit" would take the authorship from is not there.

Pin it next to its siblings.  Letting the ref be written under
--no-commit when the pick conflicts leaves the rest of the cherry-pick
tests green, so nothing else guards that path.
