Send events when creating entities in multipart post

[rschev]

Spring content creates entities when using multipart post. However, it didn't send events for onBeforeCreate and onAfterCreate, so when you have custom validation you would bypass it with the multipart.

I am always in two minds about how to test these things. I see you made the test single-threaded to ensure no other tests are publishing events at the same time. This always makes me a little sad but I dont really see a good way to test under multi-threaded conditions so ¯_(ツ)_/¯ I guess

Thanks much @rschev

Yeah, setting it to single-threaded seemed like the simplest way to accomplish this. I suppose I could've also tried to check that the list of events at least contained one with a value unique for that test, and ignored the other events.
