LivestreamLink: fix flicker when a child updates

## Ticket
1358 - flicker on livestream tile when viewers updates

## Change
Defining the component that way results in unique Card wrapper on each resolve, so everything gets torn down and re-mounted, causing the flicker.

There is a css side-effect though: the tags changed from red to black. But tags are inconsistent through the app ... sometimes black, sometimes red (I think it should always be red + smaller font from the body).
