Error when getting the list of operations and at least one operation is not found

When, by mistake, the configuration references an operation that does not exist (not deployed on the server), getting the list of available operations fails. For example:

• Nuxeo Drive client cannot connect to the server (even if the missing operaiton is not related to Nuxeo Drive)
• Using {server}

  /nuxeo/site/automation/doc fails

Both fails with an error 500, server.log shows the error is linked to the missing operation (org.nuxeo.ecm.core.api.NuxeoException: org.nuxeo.ecm.automation.OperationCompoundException: No operation was bound on ID: Retention.CreateRule)

Typical example of mistake: Add to Studio registry an operation of a plugin that is not deployed on the server.

Instead of failing on everything, the platform should return the list of deployed operations, and display a warning (or an error, I don't know) about the missing operation(s)
