While retesting #5544, I found that I get the wrong publisher info on the rewards panel in certain cases.

Steps to Reproduce

1. Clean profile, launch with staging, enable rewards and claim grant
2. Open https://www.reddit.com/user/jsadler-brave
3. Tip the publisher
4. Click the tweet button from the thank you area of the banner
5. On Twitter page open Brave Panel

Actual result:

Panel shows info for previous tab (reddit/jsadler)

We just need to add /intent/ to the list of excluded pages in our Twitter Greaselion script.

This isn't just happening on Twitter. The wrong publisher is also displayed when simply browsing random posts on the Brave subreddit.

You can see that posts are randomly attributed to CryptoJennie.

Is this the same bug?
