"Open in LBRY" links should point to a permanent URL not vanity URL

Here's an example image posted by spee.ch:
https://explorer.lbry.com/claims/94377e61712adf54ee2b78122d552682ac7d843f

It's not controlling the vanity name, because I just outbid it with a text file. The link on explorer should go to the image, not my text file. However, it goes to my text file.

Start by reproducing the example claim URL and trace where the explorer generates its “Open in LBRY” link. Done means the link targets the specific permanent claim rather than a vanity name that can be reassigned.
