Title: Starting from saved state skips setUpShares

When trying to start from saved state, virtualbox.setUpShares() fails while running:
```
VBoxManage guestproperty set boot2docker-vm /VirtualBox/GuestAdd/SharedFolders/MountPrefix /
```

The error message gives a hint: `VBoxManage: error: The machine is not mutable (state is Saved)`

Fixes #292
