Feature proposal have_applied(...events).only

Posted originally by @paneq

One of the best additional features of testing with domain events is the ability to check what has not happened.

Currently have_applied and have_published use RSpec::Matchers::BuiltIn::Include matcher which does not guarantee there this and only this. That's especially important in terms of have_applied.

It would be nice to have API such as expect(obj).to have_applied(...events).only and to know that there are those and only those events listed in unpublished_events.

Maybe only should be a default behavior even? and .softly or .not_exclusively should to it otherwise?
