* test: restore loadBucketMetadataFromFiler stub after TestGetBucketMetadata

TestGetBucketMetadata replaced the package-level loadBucketMetadataFromFiler
with a stub that sleeps one second per load and never restored it. Every
test running after it in the same binary paid that sleep on each bucket
metadata cache miss: TestPutObjectUploadACL (~245s) and
TestCopyObjectDestinationACL (~46s) each created a fresh BucketRegistry per
subtest, so the stub fired hundreds of times. In CI this stretched the
Test job past 11 minutes and left it exposed to runner cancellation.

Restore the real loader via t.Cleanup so the slow stub is scoped to the
test that needs it.
