MPS-20541 Undo is broken
Merge remote-tracking branch 'origin/master' into 3.2/editorUpdater
correcting null-pointer exception (visible if one set edited node to null, e.g. after undo in inspector - see InspectorTool.inspect() method implementation).
optimizing requestRelayout() method
calling relayout for the root cell before paining it. Necessary for the following situation: you delete name of the variable, so "<no name>" error label is displayed, but the editor itself was just synchronized, so corresponding label cell was marked as "needs relayout". Without this code editor will not paint such cell correctly.
- removing MySNodeUndoableAction - now all errors are stored inside memento and will be restored after undo automatically.
- reverting all error cells to restore them from the memento on setting memento. Necessary to completely restore error cells from the memento after undo in case there were some error cells, but they should be removed.
