After introducing userWorkspaceId into JWTs, we were wrongfully
executing
```
const userWorkspace = await this.userWorkspaceRepository.findOne({
where: {
id: payload.userWorkspaceId,
},
});
```
which would return a random userWorkpace if `payload.userWorkspaceId` is
undefined.
All generated JWTs have had a userWorkspaceId for more than a week now,
but in tests we had not modified the accessToken in use, which did not
have a userWorkspaceId, until [this
