Bug in setting RegistryRoot in Registry_ record

[wixbot]

In order to add a registry key, I was trying to use Registry_ record and found a problem setting RegistryRoot.

The problem is in the index used for set:

In blob/develop/src/DTF/Libraries/WindowsInstaller.Linq/Entities.cs

public RegistryRoot Root
        { get { return (RegistryRoot) this.I(1); } set { this[0] = ((int) value).ToString(); } }

The index to set this[0] should be this[1]

..set { this[1] = ((int) value).ToString(); } }
