Not postponing expecting Pilfer when swiping to overview.

TAPL was expecting pilfer upon UP in the swipe-pause-to-overview gesture.
Actual Pilfer happens earlier, which resulted in wrong sequence-mismatch diags if the gesture fails before UP.
Now expecting Pilfer earlier.

Also fixing a problem that sneaked through earlier reviews when even down time was passed incorrectly.
