WSOD - "workflow_eca.subscriber": Parent definition "eca.default_event_subscriber"

@sriharsha.uppuluri: thanks for the bug report, can you tell me what version of Core and what version of ECA you are using? This module was built against the now-older version 1.x branch of ECA.

This is a problem when using ECA v2.
In several cases, ECA adds, then removed a referenced interface definition.

This is fixed in the more generic 📌 Adapt to upcoming 1.9 release of Workflow Active
