The number of props to pass is getting out hand, so just pass the Comment object directly.
Also, moved the "is my comment" check into LivestreamComment, so we don't need to pass it as a prop from the parent.
As long as the input parameters are the same, the selector will return the cached value so that we don't construct the list twice, which involves blocklist filtering.
`selectMyActiveClaims` includes pending claims, so it gets invalidated often.
For the case of comment-filtering, we don't care about pending or abandoned own claims.
Only picking components that are involved in a livestream for now. Ideally, all usages of `makeSelectClaimForUri` should be replaced -- will do it incrementally.
## Ticket
6879: Previously pinned livestream comments show as latest
## Issue
`comment.List` will always display the pinned comment first, hence the problem when the chat is refreshed.
## Approach
Completely split pinned comments from top-level comments in the Reducer, and the let the GUI (e.g. regular comments, livestream comments) decide how they want to display it.
For the case of livestream, there is no need to repeat the pinned comments in the regular chat area, since there is a dedicated area on top.
* Fix ability to delete own comments in livestream
## Issue
5832: can't remove own comments in live stream mode (if you have multiple channels?)
Looks like it was just missing `commentIsMine` for the new component.
* Disable editing livestream comments
It doesn't do anything at the moment, anyways.
* Disable deleting hyperchats
The "total tipped" will get deducted when hyperchats are deleted, which doesn't make sense (doesn't reflect actual total that the creator received).
