[BUG] Live hotnesses may not be loaded correctly

[YunzheZJU]

Describe the bug
When the popup is open and a current live is ended, a locally made fake ended live without hotnesses will be pushed into the ended lives list. If the ended live's real data has already been loaded into the ended lives list, it will be replaced by the fake one, because repeated live ids will be removed.

Expected behavior
The ended live with hotnesses should stay.

Additional context
Removing repeated live ids is a patch behavior for the case where a live may be reopened after ended. In that case, multiple fake ended live with the same id will be created which may affect the UI rendering.

I think this is an issue suitable for new contributors.
