:bulb: Maybe declare a helper method in `spec_helper.rb` to easily stub the JSON file in our test cases?

```ruby
def stub_plugins_json(json=nil, status=200)
  json = File.read(fixture('plugins.json')) unless json
  stub_request(:get, Command::Plugins::PLUGINS_URL).to_return(:status => status, :body => json, :headers => {})
end
```

Then we could replace every pair of `json = File.read(fixture(...))`+`stub_request(...)` (like here but also in multiple other bacon tests) with a simpler call to `stub_plugins_json`
