Prior to the fix for SERVER-33437, the DecorationRegistry destroyed decorations in the reverse of the order in which they were constructed. This was by design, to allow for a system in which decorations could be declared on a registry in a certain order, and a developer could expect decoration construction and destruction to proceed in an order similar to regular member variables – constructed in order of declaration, destroyed in reverse order.

We should restore that ordering, in case anyone wishes to depend on it in the future, and we should test for it.
