Fix ListView not moving during catch

Fixes: 189294917

When a ListView has clickable items in it, the over scroll
animation "catch" wasn't properly catching. The problem was
that the over scroll animation was checked and the touch mode
was set, and the touch mode was checked later. Unfortunately,
the touch mode variable that was checked was different from
the one that was set.

Test: manual and new ListViewTest
