fix: harmony: Try other tasks when storage claim fails

Proposed Changes

Before this fix if considerWork was called with a bunch of tasks, and the one selected first by CanAccept was consistently failing to claim storage, we'd get stuck never trying to claim other tasks. Combined with the bug in storage reservations (#11825) this could lead to pile-ups which would make everything clog up, and no tasks would get executed.
