test: correct the auto-disable fence test's premise

The previous version claimed a stale run could disable a schedule the owner had
re-enabled, and reproduced it by calling updateScheduleById directly. That
bypasses the handler, which zeroes failureCount/balanceSkipCount and clears
disabledReason on re-enable, so a re-enabled schedule cannot be sitting at the
threshold — the state the test constructed is not reachable through the API.

What the revision fence actually closes is the read-then-write window in the
auto-disable policy itself: it re-reads the schedule and then writes, so an owner
edit landing between the two rotates configRevision under a decision already
made. The test now reaches that state the way it is actually reachable, via a
plain rename that deliberately leaves the counters alone.

+   * decision no longer applies.
