Cucumber/rspec doesn't work in sublime with a project with custom folder structure

If I have in my sublime project the test folders like this

```
{
"folders":
[
  {
    "path": "features"
  },
  {
    "path": "spec"
  },
  {
    "folder_exclude_patterns":
    [
      "features",
      "spec"
    ],
    "path": "/home/guda/something"
  },
]   
```

Then the cucumber/rspec doesn't find the project root.
