Exception for job details if object not set

[alehaa]

Deployment Type

Self-hosted

NetBox Version

v4.1-beta1

Python Version

3.11

Steps to Reproduce

1. Create a new JobRunner.
2. Schedule the job runner without an instance being passed to enqueue().
3. Navigate to jobs view
4. Open List item for newly created job

Expected Behavior

Job details are shown.

Observed Behavior

An exception is raised due to accessing _meta of the Job's object. However object is None as scheduled above.

This is due to 3028f26 introducing breadcrumbs for jobs. However, d6432fb introduced the job object being optional around the same time.
