Check for string containins scopes and use string representation instead

[pLeminoq]

With the upgrade to MQTT we got rid of the RSBScope type and use our proto type everywhere. We should make sure that every time this scope is used in Strings, we use the ScopeProcessor.genererateStringRep method, since the raw to string method produces a multi-line string.
Example where this needs to be fixed:

• jul/communication/controller/src/main/java/org/openbase/jul/communication/controller/AbstractControllerServer.java

  Line 1249 in 93af28e

  return getClass().getSimpleName() + "[" + publisher.getScope() + "]";

Example where it is correctly used:

• jul/communication/controller/src/main/java/org/openbase/jul/communication/controller/AbstractRemoteClient.java

  Line 1717 in 93af28e

  return getClass().getSimpleName() + "[scope:" + ScopeProcessor.generateStringRep(scope) + "]";
