Disable Template Cleanup in MultiVersionRepositoryAccessIT

Not the most elegant solution, but we do not clean up templates in
x-pack REST tests either it seems. I don't think it's worth it working
out all the details for pre-7.8 versions here when we can just turn
off the template cleanup and have tests working fine for older versions.
