When apps are eager loaded (see #4889), this should not happen anymore. But as the other PR needs some additional testing, this one should be merged as a quick fix. |

A short explanation of the proposed change:
Nil guard prevents exceptions "docker? delegated to app, but app is nil" when listing large number of processes on a live system. The exception can happen if ProcessModel objects are processed while the associated app is being deleted.
