[HotChocolate.Data.UseFirstOrDefault] causes an exception: EXEC_LIST_TYPE_NOT_SUPPORTED

[arminneman]

[HotChocolate.Types.UseFirstOrDefault] has been moved to [HotChocolate.Data.UseFirstOrDefault] in v11(rc0 and rc1), but the latter gives an exception: EXEC_LIST_TYPE_NOT_SUPPORTED
The type '...' is not supported as list value.

The [UseFirstOrDefault] attribute should automatically set the return type as instead of IEnumerable

To Reproduce
Steps to reproduce the behavior:
server side:
[HotChocolate.Data.UseFirstOrDefault]
[HotChocolate.Data.UseProjection]
[HotChocolate.Data.UseFiltering]
public IQueryable GetUserGroupById([Service] EherkenningDataContext context, Guid id) =>
context.UserGroups.Where(p => p.GroupId == id);

client side:
query {
userGroupById (id: "e003c8c1-3310-4a58-9baf-08d880a18656") {
groupId
}
}

same behaviour occurs with SingleOrDefault

Expected behavior
It should return a single result
