Pro entity detailed view: RERO data missing

[PascalRepond]

Bug description:

With the new version of MEF, data.rero was stopped and RERO identifiers have been deleted so the UI tries to display the RERO data but encounters an error:

Expected behavior:

Filter so that MEF data from RERO entities is not displayed in the detailed view (pro UI).

Steps to Reproduce:

1. Go to any entitiy detailed view that has RERO as source (ex: https://ilsdev.test.rero.ch/professional/records/remote_entities/detail/12613196)
2. See problem

Context
