Bugfix [#34869] Switching actions does not trigger animation refresh

Changing actions via RNA (or apparently from the Action Editor browse menu too)
didn't perform all the necessary updates/tagging/recalc needed to have the
results of the new action get immediately applied in the 3D view. This caused
problems for exporters, as the first frames exported would be incorrect (though
this could probably be worked around by manually stepping the current frame
forward one frame then back again).
