This change means that a service provider may use both the Frozen
specimen builder and also the 'with autofixture resolution' behaviour.
That means that some unwanted extra logic in the test may now be
removed, with the test objects also coming from Autofixture.
This now also includes reworking the attribute which activates
Autofixture-style resolution upon an IServiceProvider.
This has now been renamed to WithAutofixtureResolutionAttribute.
The new/reworked attribute is composable with other Autofixture
attributes.
This extension method is quite complex and is frustrating
when a unit test passes-through it. That's because extension
methods can't be mocked in tests.
The triggers-for-activity-blueprint functionality
is quite complex just on its own, so I have moved this to
a new service.
Once again the integration test which is left behind proves
that it still does the same job.
