incorrect Twitch link in auto contribute and tips tables

[LaurenWags]

Description

When visiting a twitch page (ex. twitch.tv/psherotv), the channel is correctly added to the AC table, however the link for the channel is incorrect. The link should be https://www.twitch.tv/psherotv/videos however it is actually https://www.twitch.tv/psherotv/videos/videos. If you continue to revisit the page (either in a new tab or refresh the existing tab) another /videos will be appended to the link, so it's pretty easy to end up with a link like https://www.twitch.tv/psherotv/videos/videos/videos/videos/videos.

This is occurring on release channel version 0.65.120 but not on 0.65.118 (currently released version).

Steps to Reproduce

1. Install 0.65.120 and enable Rewards.
2. Visit a twitch channel such as https://www.twitch.tv/psherotv (I think this has to do with live streams, but should check VODs as well)
3. Wait for channel to be added to AC table.
4. On https://www.twitch.tv/psherotv/ refresh the page a couple of times.

Actual result:

View your AC table and hover over the entry for psherotv:

Expected result:

Link should not change when you refresh or revisit the page.

Looks like twitch doesn't redirect https://www.twitch.tv/psherotv/videos/videos, but will redirect something like https://www.twitch.tv/psherotv/videos/videos/videos/videos/videos/videos.

Link is still wrong, but it seems to have less of an impact.

It seems that publisher_info_db becomes corrupted with the wrong url.

Additional way to reproduce:
Watch a livestream. As the attention % on your AC table increases, another /videos will be added to the URL.
