BlueOcean UI subscribes to SSE event without providing organization in the subscription filter.

There are couple of places it needs to add jenkins_org in the sse subscription filter:

• SseBus.js
• SSEService.js

For example:

this.jobListener = this.connection.subscribe('job', (event) => {
                this._handleJobEvent(event);
            }, {
    jenkins_org: 'org-1'
});
