enableLocationRequest does not return on enabling or denying

It does resolve if location is already enabled.

But it does neither reject if location permission is denied or resolve if permission was granted and location was enabled.

Or am I doing something wrong?

```
geolocation.enableLocationRequest()
  .then(resolved => {
    console.log('resolved')
  })
  .catch(rejected =>{
    console.log('rejected')
  })
```
