ClaimLink: skip blacklist check (#329)

## Issue
- It was checking the blacklist on every render.
- Finding opportunities to improve performance

## Changes
Since the final destination will be a dead end anyways, skip the blacklist check so that livestreams can render a bit faster when there lots of mentions.

The only downside is that a claim preview for a blacklisted item would now appear (vs. being a text previously)
