BPM: incorrect work if process name is null

[stasmakarov]

Environment

Jmix version: <2.3.4>

Process name is not mandatory, so it can be empty. But the system must work correctly in this case.

1. Notification when process starts:

2. If the process name is empty (null), it causes NPE when user opens the task.

Steps To Reproduce

Create process without name, only id:

Deploy and start it.

Expected Behavior

1. In notification use process id if name is null
2. In My Tasks: in the tree element use process id if name is null
3. Allow to open and complete the user task

Sample Project

Attach a zip-archive with a sample project or provide a link to a GitHub repository with a minimal, reproducible example.

Jmix Studio Toolbar provides an action for creating a zip-archive from your project.

Reports that include a sample will take priority over reports that do not.
