404 When force_create repo -> Not inserting Org Name

## Problem Description

Working to prototype and implement safe-settings. While working through the bug, I created blank settings.yml, suborg file and a new repo file under .github/repos/test-repo.yml.

When creating a new yaml file for a repo and setting force-create to true, it throws a 404 when attempting to create the repository.

### What is actually happening

When the application is trying to do an HTTP Post to github it is getting a 404. The 404 is caused by the URL not having the org name in it.

status: 404
request: {
method: "POST"
url: "https://api.github.com/orgs//repos"

### What is the expected behavior

Repository is created

### Error output, if available

```
status: 404
request: {
method: "POST"
url: "https://api.github.com/orgs//repos"
headers: {
"accept": "application/vnd.github.nebula-preview+json",

"authorization": "token [REDACTED]",
"content-type": "application/json; charset=utf-8"
}

}
}
```
