Fix splitExpensesTotal to use all children before filtering deleted ones

splitExpensesTotal was computed from remainingSplitExpenses (already filtered
to exclude deleted transactions), making changesInReportTotal = sum(remaining)
- sum(remaining) = 0, so the report total never updated. Now compute it from
allChildTransactions (before filtering) so the delta correctly reflects the
removed amounts.
