"dnu publish" runs scripts for published project

[anfomin]

After some recent change dnu publish invokes command in next order:

1. Restores packages which causes scripts invocation from project.json.
2. Publish to destination directory.
3. Restores packages for published project to write project.lock.json.

I've next scripts configured:

{
    // from project.json
    "exclude": [
        "wwwroot",
        "node_modules",
        "bower_components"
    ],

    "publishExclude": [
        "bin",
        "obj",
        "node_modules",
        "bower_components",
        "bower.json",
        "package.json",
        "gulpfile.js",
        "**.xproj",
        "**.user"
    ],

    "scripts": {
        "postrestore": [ "npm install" ],
        "prepare": [ "gulp default" ]
    }
}

Third action invokes scripts from project.json again. This causes error in npm install and gulp default because published directory does not contains package.json, bower.json and gulpfile.js.
