splitview: Fix animation not showing up when exiting overview.

[1] changed overview to release overview session and then pass that
object to its observers. Splitview was querying overview controller
for overview session which would be null, so it wouldnt remove the snap
window from overview list, which would cause its animation to be
supressed.

This cl change splitview to remove the window in OnOverviewEnded and
use the overview session object before snapping.
