files in git not within source_root forcing check_pending to setLastProcessedRef

[ewah]

files not the source_root will go into check pending.

    if (branch.source_root && record.path.indexOf(branch.source_root) !== 0) {
      return check_pending();
    };

and the pending_records is ALWAYS decrementing.

--pending_records
