Extra data returned by tip comment endpoint

[davidyuk]

In the example below the child comment is in both the root list of comments and in child comments. This may bring a significant amount of extra data in some cases, so I propose to choose one way and drop the other one. Currently, in superhero-ui used nested comments and their duplicated are filtered out.

One more inconsistency is that the Profile key (by the way, why it from the capital letter?) defined in the root array elements, but missed in children comments.

Interestingly, the comment replies endpoint places children once in nested arrays. For example, "great!" reply in https://raendom-backend.z52da5wt.xyz/comment/api/756
