lists/migrate3x: change root package for replan to tos3to4-early
This solves issue that tos3to4-early depends on switch-branch and that one depends on updater-supervisor and that one depends on updater-ng. In the end that creates with additional dependency of updater-ng on tos3to4-early cycle dependency and updater won't allow that with critical package.
This just uses tos3to4-early for same purpose as previously updater-ng. It is just rude fix to break cycle.
