split: preserve phase of commit that is being split...

split: preserve phase of commit that is being split With this change, hg split will preserve the phase of the commit that is being split, ignoring the phases.new-commit setting. Previously, we would use whatever phases.new-commit was set to (unless our parent was secret, then we would be secret even if phases.new-commit=draft). Now, splitting a draft commit with phases.new-commit=secret does not cause the new commits to become secret, and splitting a secret commit with phases.new-commit=draft and a draft parent does not cause the new commits to become draft. Test cases and commit message taken from Kyle Lippincott's D2016 (thanks!). Differential Revision: https://phab.mercurial-scm.org/D3819
