Edited Issue: ArgumentNullException in NodejsProjectNode.WriteReferenceFile crashes Visual Studio 2012 [683]

Exception details below.

Steps to reproduce:

1. Download Christophe Conraets' NodeCellar sample app to a convenient folder with "git clone https://github.com/ccoenraets/nodecellar".
2. Create a new project from existing node.js code, pointing the wizard at the nodecellar folder. Use default settings for the remainder of the wizard.
3. Expand npm node - note, as expected, missing modules.
4. Right-click npm node and click "Install Missing npm Modules"
5. npm will install the modules and the exception will occur.

I don't know how reproducible this is. It may be a race, since the call stack originates with the FileSystemWatcher.

The problem is that the filename parameter is null. NodejsFileNode._tempFilePath is passed in as the value of this parameter.
