Fix T37886: Material does no update when changing keyframes in dopesheet

It was a missing fcurve evaluation in scene update function which lead to
materials only being updated on frame change.

Added the same exception as we've got for the scene animation. It only
runs when there're materials tagged for the update, so wouldn't expect
speed regressions or so.
