Use Job name instead of a reference to the address in memory.

[njbrake]

What's changing

Use the record's name, because otherwise it logs the class name and memory address.

Before change:

.....- Obtaining info for job ca7c4a26-2c45-4e8e-9ce6-ae1abc9b2a49: <backend.records.jobs.JobRecord object at 0xffff713e8a90>

After Change

....- Obtaining info for job ca7c4a26-2c45-4e8e-9ce6-ae1abc9b2a49: nathans_job

How to test it

Steps to test the changes:

1. make local-up
2. upload dataset
3. trigger a job, and look at the backend logs.

I already...

• Tested the changes in a working environment to ensure they work as expected
• Added some tests for any new functionality
• Updated the documentation (both comments in code and product documentation under /docs)
• Checked if a (backend) DB migration step was required and included it if required
