Shape tracing doesn't display wrappers (OSOE-340)

[mvarblow]

Thanks for sharing these helpers! The shape tracing helper really filled a need for us. However, one thing I noticed... it doesn't seem to report wrappers. I think the problem is that OrchardCore processes and then clears the wrappers before firing the Displayed event that the shape tracing module hooks into.

Wrappers are cleared here:

But the displayed event is fired just a bit later, here:

Thanks for the details, Matt! It seems indeed that's the case. I'm not sure how to solve this, however. The Displaying event is invoked earlier, however, that's where wrappers are commonly added (like DynamicCacheShapeDisplayEvents and MediaShapes) so unless the Helpful Extensions feature depends on everything else, it won't necessarily see all the wrappers (or maybe we can get it run after everything else with Startup.Order.
