CORDA-1837 - Reject nodes that have the same organisation name in driver tests (#3740)

* Reject nodes that have the same organisation name as a previously registered node rather than the same X500 name

DriverDSLImpl -> NetworkVisibilityController -> register check organisation name rather than X500 name and throw IllegalStateException if already exists
Added test to DriverTests to test multiple organisation names end exceptionally

* Remove redundant test and store the organisation names rather than X500 names for driver tests
