Fix column swiping animation logic (#15301)

Fix column swiping animation logic (#15301)

From the start, swiping columns was highly unreliable because the logic
could change `ReactSwipeableViews`'s `animateTransitions` property
mid-swipe.

PR #11200 partially fixed this, but at the unintended cost of disabling the
swipe animation altogether.

This PR changes the logic behind `shouldAnimate` to only disable the swiping
animation at the end of a column change not initiated by `ReactSwipeableViews`.
