Reland "Fix undo / redo filling with empty steps" (#1653)

* Revert "Revert "Fix undo / redo filling with empty steps (#1649)" (#1652)"

This reverts commit 7623810166.

* Update test expectations

* Add dirty flag if workflow is not persisted

* Add dirty flag to other UI areas for new workflows

* Remove redundant code

* Fix regression: undo / redo steps lost on refresh

The history is still be cleared, but any changes made by issuing undo / redo comands prior to refresh are not lost.

* Update test expectations

Partially reverts f8cc2c0d67 - adds dirty flags back to unsaved workflows.
