[CORDA-442] make MockNetwork not start a networkmap node (#1908)

* [CORDA-442] make MockNetwork not start a networkmap node

Now MockNetwork will put the appropriate NodeInfos inside each running node networkMapCache.

Tests relating to networkmap node starting and interaction have been removed since they where relaying on MockNetwork
