Project name is not very clear in notifications for multi-branch pipeline projects

[yrodiere]

When I use the ZulipNotifier in a multi-branch pipeline project, I get notifications that look like this:

Project: production : Build: #1: SUCCESS

Project: staging : Build: #3: SUCCESS

The "project name" in these examples is in fact the branch name. That's because, for multi-branch pipeline projects, one sub-project is created for each branch, and this sub-project has the same name as the branch.

This notification message is not very clear, since it doesn't allow to identify the failing Jenkins job.

Ideally we should make the message clearer?

• What Operating System are you using (both controller, and any agents involved in the problem)?

RHEL 8 on controller, Fedora 34 on agents.

Reproduction steps

• Create a multi-branch pipeline project
• Set up Zulip notifications in that project
• Trigger a build and check out the notification

Results

Expected result:

The notification should include the project name and branch, e.g.:

Project: hibernate.org » production : Build: #1: SUCCESS

Actual result:

The notification does not include the project name, only the branch name, e.g.:

Project: production : Build: #1: SUCCESS
