MWCP: Use the event store logic when all discussions are resolved
The following discussion from !146153 (merged) should be addressed:
Currently when we resolve the discussions, we are manually running the AutoMerge service, but once we move MWCP to FOSS, when resolving discussions, it would be better to use the event store logic to be in line with the other checks, rather than calling auto merge service directly.
