tests: rename 'test-module-import.t' into 'test-check-module-import.t'

tests: rename 'test-module-import.t' into 'test-check-module-import.t'

This test is checking our source code to ensure style and correct behavior (eg:
no cycle). Current convention is that such tests starts with 'test-check-' so we
flock this on back with the others.
