There was a datarace caused by deleting the builtinprotocols of the RTPSParticipant when it was being disabled while the same builtinprotocols were being updated by the file watcher. This fix prevents the file watcher from iterating over the participant being deleted by first removing it from the RTPSDomain participant list and subsequently disabling it.
