Title:
RSS feeds for repositories owned by organizations have duplicate entries
---
Description:
The RSS feeds for repositories owned by organizations have several duplicate entries with different GUIDs, cluttering feed readers and reducing the number of unique items available in a feed. I originally ran into the bug on https://git.mills.io/yarnsocial/yarn.rss and did some testing in different contexts to try and find a pattern. The bug is definitely related to repositories owned by organizations, but the number of duplicates differs between repositories. The results of my tests are displayed below.

```
URL							Instance Version		Duplicates?	Notes
https://git.mills.io/yarnsocial/yarn.rss		1.17.0				Yes		Original finding
https://git.mills.io/yarnsocial/yarn.social.rss		1.17.0				Yes		Same organization, different repository
https://git.mills.io/saltyim/salty.im.rss		1.17.0				Yes		Same instance, different organization
https://git.mills.io/prologic/gonix.rss			1.17.0				No		Same instance, but repository owned by a user
https://try.gitea.io/0000000000/aaaa.rss		1.18.0+dev-350-g8bbb622bb	Yes		Demo instance, repo owned by an organization. 
https://try.gitea.io/UpYoursMicrosoft/foobar.rss	1.18.0+dev-350-g8bbb622bb	No		Demo instance, repo owned by a user
```

I had to use an existing repository owned by an organization on the demo instance because I was unable to create an organization myself.
