It seems a little inconsistent to have Emma be heroic in Jessica Jones and a villain in Uncanny. I think a lot of people are making assumptions about what is going on in Uncanny 18, it's possible that Cyclops and Wolverine go to Emma for help. They might play up the initial meeting with Emma being all "regal" to greet them. With her positive portrayal in JJ Purple Daughter, I think maybe that Marvel isn't planning to make her into an outright villain after all.
