Undo of deleting a property does not restore a view grouped by it #1324

Steps

1. Create a text property "note" and set it on a few blocks.
2. Add a table view and group it by "note".
3. Delete the property "note".
4. Press Ctrl+Z.

Expected

"note" is back, and the view is grouped by "note" again.

Actual

"note" is back, but the view is no longer grouped: its "group by" setting stays empty.

Notes

The view's group-by setting (:logseq.property.view/group-by-property, type :property) is a reference to the property entity, so deleting the property removes it. The undo re-creates the property but does not restore references to it from other nodes (#1338, same family as logseq/logseq#1311). The view's sort and filter settings store the property as a value, not a reference, so they are not affected.

Found with a probe of undo on single operations, replayed on upstream master 16c4ed1a0: before the delete the view's group-by is :user.property/note; after the delete and after the undo it is empty.
