Handling of autoupdate `receivedData` rejection

[bastianjoel]

Currently we do not take into account that a autoupdate subscription could fail. This got relevant now with the ability to pause the autoupdate service.

Especially the implementation of ModelRequestService.waitSubscriptionReady could be improved to be more error resistant. Also usages of ModelRequestService.fetch currently all ignore that the promise could be rejected.

This issue needs to be addressed before things like loading bars in list views or similar things can be implemented.

@bastianjoel should this get a higher prio? or a prio in general?

[bastianjoel]

Yes, it might make sense to fix this at some point.
We have some other things like fixing the linter errors in the shared worker and #2933 where it might make sense to do those in one batch.
