TEST_REGISTRY doesn't have all the tests in it

When importing TEST_REGISTRY from fil_actors_integration_tests, there seems to be a non-deterministic number of tests that were actually added by the proc-macro.

Possible causes to investigate:
- order of proc macro triggering in dependencies
- how proc macro's and lazy_static complete in order?

Start by reproducing the non-deterministic TEST_REGISTRY contents when importing fil_actors_integration_tests. Inspect the proc-macro triggering order and how proc macros and lazy_static complete; done means TEST_REGISTRY deterministically contains all proc-macro-added tests.
