removing './' from component.json

this is a problem with `component-build`, but figured it'd be easier to fix here...

when using `proclaim` as a dep of a component, we'll get this exception:

```
Uncaught Error: Failed to alias "rowanmanning-proclaim/lib/proclaim.js", it does not exist 
```

as the actual path to `proclaim` is `rowanmanning-proclaim/./lib/proclaim.js`.
