When cherry-pick fails it offers a helpful hint about how to proceed. The hint tells the user how to do the cleanup needed by the conflicted cherry-pick and finish the job after conflict resolution. In case of cherry-pick --no-commit, the hint goes too far. It tells the user to finish up with 'git commit'. That is not what this git-cherry-pick was trying to do in the first place. Restrict the hint in case of --no-commit to avoid giving this extra advice. Also, add a test verifying the reduced hint for the --no-commit version of cherry-pick.
