fix(delegate-job): logs passes --registry-dir on only when given (Issue #57, Mac F2)

cmd_logs always passed the wrapper's cwd-relative default registry, so the
usual run (registry not moved, cwd not the workspace) no longer found its
jobs. Without the option registry.py's own default decides, as before:
MAM_JOBS_DIR, then WORKSPACE_ROOT, then the cwd.
