Summary: Fixes a bug noted here: https://grist.slack.com/archives/C069RUP71/p1662564341132349 This bug could happen quite easily as follows: 1. Have a formula in a summary table such as `$group.amount`. Typically there's also a `SUM` but that's not essential. 2. Find a group with nonzero values of `amount`. 3. Delete all rows in that group in the source table. Typically that just means one row in a lonely group. 4. The summary table row is automatically deleted. 5. Try to undo. This raises an error about trying to update a non-existent summary table row. I tried to account for this undo problem in https://phab.getgrist.com/D3489 by not saving the updated value for `$group` when it was found to be empty. The reason this was insufficient is that `$group.amount` is immediately invalidated anyway when the source row(s) are deleted (I think because that's just how dependency relations involving references work) *and* the calculated value of `$group.amount` changes even if `$group` doesn't. For example, `$group.amount` may have previously been `[100, 200]`. After deleting the rows, `$group.amount` becomes `[0, 0]`. Keeping `$group` unchanged prevents `$group.amount` from just being `[]`, but deleting the source rows means that the amounts become the numeric default `0` which is still a change. This change in value is then noted which leads to saving an undo action to update the summary table record. All this happens in step 3 above, and the summary record is only deleted after that point. This diff removes that special handling for `group` and instead adds a more general fix to `action_summary.py`. This inserts undo actions for deleted rows at the beginning of the undo list rather than at the end, which was already done for deleted tables and columns.
