[Fix] UI link description to use metadata.link_name if it's set

[viniarck]

Fixes #12

Release notes

Changed

• Changed UI k-select links items description to try to use link.metadata.link_name

Heads up: We'll probably need to do the same for the interfaces list, I'll map this one as soon as it's confirmed

Testing locally

• If link_name isn't set it'll still fallback to use id, as you can see below we have two links and only one has link_name set:

Thanks for reviewing, guys.
