Default ask() to No if Eof is thrown

This is a minor cosmetic change for cli tools that defaults to No if the `ask` method is called and Eof is thrown.

**Previous output**
```bash
Set <project> to version x.x.x [y/n/a] ? Eof
```

**New output**
```bash
Set <project> to version x.x.x [y/n/a] ? n
```
