Answer 1

To re-install this app you need to access the store and re-install it, however it's not available in the Dev preview.

If you need to get it back, you can refresh the system.

Answer 2

Unfortunately, there is no way to reinstall specific applications on the Windows Developer Preview.

However, you can return your machine to the original state (including apps) by going to the control panel, General, "Reset your PC and start over"
