No streams in web interface after update

With configuration

```
api:
  base_path: "/go2rtc"
```


browser says:
```
(indeks):136          GET https://host:8123/go2rtc/api/streams 404
SyntaxError: Unexpected non-whitespace character after JSON at position 4
```

And there is no streams listed - nor defined in `streams:`, nor defined in home assistant. Version v0.1-rc.8 was working fine
