Don't include transient launches in visible-at-end tokens

visible-at-end is supposed to track apps which are expected
to be visible at the end of a transition. However, transient
launches are temporary so their visibility is likely to change.
Because of this, don't track them as visible-at-end so that
their new visibility is actually committed.

Bug: 226673164
Test: go to split, swipe to overview, restore split, check
      logs and make sure launcher has committed invisible.
