wizard mode buglet: simultaneous Lev+Fly timeout

Noticed while working on Qt status highlighting:  if levitation
and flying timed out at the same time, first Lev timeout called
float_down() which reported
 You have stopped levitating and are now flying.
and then Fly timeout left stale "Fly" on the status line due to
an optimization which got subverted.  ('was_flying' flag was
False due to Fly being blocked by Lev; that's correct behavior,
but the flag is effectively a cached value that becomes stale
when the Lev timeout code executes.)

The bug was wizard mode only because #wizintrinsic is the only
way to get timed flying.
