satis build trying to connect to github

I've deployed several packages with satis, so this worked before.

When building now, I receive this error:

```sh
[UnexpectedValueException]
Your github oauth token for github.com contains invalid characters
```

I do not host any packages on github, they should be pulled from bitbucket. This is my package.json:

```json
{
"name": "domain/packages",
"homepage": "https://packages.domain.tld",
"repositories": [
{ "type": "vcs", "url": "https://bitbucket.org/team/repo-1" },
{ "type": "vcs", "url": "https://bitbucket.org/team/repo-2" },
{ "type": "vcs", "url": "https://bitbucket.org/team/repo-3" },
{ "type": "vcs", "url": "https://bitbucket.org/team/repo-4" },
],
"require" : {
"domain/repo-1": ">1.0.0-beta.42",
"domain/repo-2": ">=1.0",
"domain/repo-3": ">=1.0",
"domain/repo-4": ">=1.0"
},
"archive": {
"directory": "archives",
"format": "zip",
"skip-dev": true
}
}
```

This is the command I use to build (which has been working for years):
```sh
php bin/satis build ../satis.json ../www
```
