support for multiple arguments is missing

[rschulz-scisys]

we use signalr not with a single payload, but with multiple arguments. The other signalr cypress plugin supported this.

    // previous implementation
    cy.hubPublish(HubOnMethod.onEntity, 'planning-lists', dataTable.hashes()[0].id, dataTable.hashes()[0]]);

The problem is, to make the tests work, we need to wrap the arguments in an object and have now a second path in the code, checking for the presence of cypress to then check if the payload has an arguments property to then handle that correctly. But we cannot change the interface of the microservices. So this is not very nice:

    // updated implementation
    cy.hubPublish('/hubs/entities', HubOnMethod.onEntity, {
      arguments: ['planning-lists', dataTable.hashes()[0].id, dataTable.hashes()[0]],
    });

The side path in the fgrontend looks similar to this:

      this._connection.on(
        'onEntity',
        (entityType: string | any, entities: Entity[], count: number) => {
          // the new cypress signalr mock can not send multiple arguments, we need to spread it
          if (entityType.arguments) {
            this.process(entityType.arguments[0], entityType.arguments[1], entityType.arguments[2]);
          } else {
            this.process(entityType, entities, count);
          }
        }
      );

I would like to avoid having t6hat separate path in the real code that is only needed in cypress testing.
