No intellisense on Express after npm install with a new project

[mousetraps]

Repro steps:

• file > new project > express 4 template
• wait for packages to install and analysis to complete
• hovering over app yields unknown type

When this issue occurs, of the top-level packages installed (the ones that appear in package.json and were installed with ), some appear to have been analyzed and some don't:

❌ body-parser: unknown type
❌ cookie-parser: unknown type
❌ debug: unknown type
❌ express: unknown type:
✔️ jade: completions available
✔️ morgan: completions available
✔️ serve-favicon: completions available
✔️ stylus: completions available

An interesting coincidence about this list is that the packages yielding unknown type are those packages sorted towards the beginning of the alphabet. This is consistently the case, and this issue appears to be unrelated to the sort order in package.json.

The express 3 template yields similar results:

❌ express: unknown type
❌ jade: unknown type
✔️ stylus: completions available

Workaround: if you install any other package, say azure, completions are suddenly available for all of the packages (including those towards the beginning of the alphabet.)

This issue also affects all dependencies of a package. For instance...

// completions for all express dependencies not available
var connect = require('./node_modules/express/node_modules/connect');

// completions for all stylus dependencies available
var cssParse = require('./node_modules/stylus/node_modules/css-parse');

This problem is currently affecting me, and I tried running:
npm install azure --save
In my project's directory but Express still does not show any Intellisense options. Installing another package (jquery) also did not help. Perhaps I am misunderstanding your workaround.
