Work around ansible issues using Browbeat-ML to classify pipeline builds

1. Fixed the bug where the browbeat_run.log file is empty.
2. UUID will now be grepped from the log file directly. Bypassing an
ansible issue that made grepping it directly from the registered result
impossible in specific situations.
