workspaceThumbnails: Update indicator on workspace changes

Browse Source 
We block state updates while the indicator for the active workspace
is animating. To track that, we check whether the scroll-adjustment's
value matches the active workspace index. That works as long as the
adjustment's value changes after the active workspace, but not when
switching workspaces via SwipeTracker which only changes the active
workspace after transitioning to the new scroll value.

To fix that, update the indicator on workspace changes as well.
