Tests now kill M09, M11, M14, M17, M18, M19, M21, M23, M28, M29, M31 (each
re-run by hand). The account locks are taken one statement each in sorted
order, so dropping the sort is observable (M01) instead of planner-dependent.
resolveAccount had no caller and answered wrongly after a chain of moves: deleted
with its docs claim; the alias test inside moveIdentities stays.
