Edited Issue: Selecting to save analysis file causes VS to crash [1421]

VS2013 Ult Update4 CTP2
NTVS 21003.02

Repro:
1. With the preset default analysis options, create an Express Web app. Wait for the analysis results to be saved to the disk.
2. Go to the Tools Options -> Test Editor -> Node.js -> IntelliSense, select "No IntelliSense" and "Don't save analysis" and Save the new settings.
3. Go to the project folder (show all hidden files) and make sure _ntvs_analysis.dat is deleted
4. Go back into the Tools options dialog (same as in step 2) and select to "Save analysis results".
5. Save the new setting.

Result:
VS crashes. There is an unhandled exception in nodejstools.dll. Callstack is attached.
