Revert "Folder: call activate on the object instead of portal_activities.activateObject in _recurseCallMethod()."

This reverts commits 3d3ec3cb ((+ fixup), which
broke recursion to objects that don't inherit ActiveObject, as explained in the
docstring.

I also think it was wrong in that default activate parameters disappear at the
end of the transaction whereas _recurseCallMethod may activate itself to avoid
creating to many activities at once. IOW, it's important that created
activities are the same no matter where _recurseCallMethod splits the browsing.

This change needed more review, as well as a unit test.
