Fix import in Accelerate for find_exec_bs
# What does this PR do?

This seems to have slipped through the cracks of the reorg in Accelerate. Should fix the import error seen in the tests.
_The documentation is not available anymore as the PR was closed or merged._<|||||>Abusing my admin right to merge this right now since all tests are green and this fixes a test failing on many other PRs :-)
