feat(cli): output relative destination paths (#312)

* [cli] output relative destination paths

Currently wide output looks bad on half of the screen I use for terminal

```
src/svgs/visibility.svg -> /Users/_________________________________________/src/icons/Visibility.js
```

In this diff I suggest simply cut useless path and get this

```
src/svgs/visibility.svg -> src/icons/Visibility.js
```

* Sort output for stable test
