modules
Summary:
Right now, if you add a file to "__tests__/data/blah.testcase" it doesn't
trigger those __tests__, but it should. Trigger __tests__ in all parent modules
when a file changes.
(We could be a little more complex about choosing what to run but all the tests
are super fast so it hardly matters if we run "too many" tests.)
Test Plan: Ran "arc unit" on this, got a test trigger. Added a file to a
__tests__/data/ directory and got a test trigger. Added some var_dump() and
spot-checked things for sanity.
