Important: A job list whose request fails shows no jobs 

Description 

The service that asks the B-ITE API for the postings kept the last response it received. On a page with two job lists, a second job list whose request failed therefore showed the postings of the first one, under its own heading and settings.

The service keeps nothing between two requests any more. A job list whose request fails shows the message that no jobs are available, and the error is logged as before.

Only pages with more than one job list are affected, and only while the B-ITE API does not answer one of their requests. The behaviour is the same on TYPO3 v13 and v14.
