Agent's csr does not show up in master cert list if agent submitted using a non-existent directory environment.

Master has environmentpath set. Agent attempts an initial request to the master but agent's environment does not exist in the master's environmentpath. Agent creates a csr, but master does not record it, responding instead with a 404 for missing environment. Agent makes a second run with the environment that exists, but csr is not submitted again, and the master has no csr to sign, so agent is in a nebulous unverified state with regard to its cert.

Work around is to delete agent's csr on the agent or its whole ssldir.
