vagrant up fails:  /app/app/bin/default-app-dir: /bin/bash^M: bad interpreter: No such file or directory

On Windows, in master branch, after `vagrant destroy` `vagrant up` fails with:
```
pv:1.2.0
/tmp/vagrant-shell: /app/app/bin/default-app-dir: /bin/bash^M: bad interpreter: No such file or directory
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

chmod +x /tmp/vagrant-shell && /tmp/vagrant-shell
```
