Fix issue #74248644: Swiping away task increments start ID of running services

The start item for reporting onTaskRemoved() no longer increments
the current start id, reusing the last one.  Instead we explicitly
disambiguate between normal starts and task removed starts (which
we should have been doing anyway).
