8764 incorrect email sorting

Closes #8764

Great thank you! Do you think we could simplify and just merge the two requests in one? I don't see why it wouldn't be possible but maybe I'm missing something. Feel free to merge after

[bosiraphael]

We can't merge the two requests because the filter

 where: {
          messages: {
            messageParticipants: {
              personId: Any(personIds),
            },
          },
        },

would apply on both and we would get only the personIds in the messageParticipants and not the other messageParticipants
