findBreakingChanges does not support extended types

[erangakm]

Old type:

extend type Report {
  displayName: String!
}

type Report {
  id: Int!
}

New type:

extend type Report {
  displayName: String
}

type Report {
  id: Int!
}

Removing the nullability on the extended type doesn't trigger a breaking change at the moment. Would be great if this is supported :)

@erangakm What function you use to build your schemas?
Is it buildSchema?
Problem is that buidlSchema simply ignores extensions node as discussed in #922.

@IvanGoncharov I'm using makeExecutableSchema

Unlike the problem outlined in the issue you linked, I can see that the type I extended in the schema working correctly. It's just I can't see any breaking changes to it when I use findBreakingChanges

@erangakm Thanks for additional info I will try to take a look.
You can help a lot if you create a small repo that reproduces this issue.
