Add tests for rebase -i --root without --onto

Test for likely breakages in t3404, including successful reordering of non-conflicting changes with a new root, correct preservation of commit message and author in a root commit when it is squashed with the sentinel, and presence of the sentinel following a conflicting cherry-pick of a new root. Remove test_must_fail for git rebase --root without --onto from t3412 as this case will now be successfully handled by an implicit git rebase -i.
