Description Michael Rennie

Steps:

1. open explorer-table.js
2. select and instance of #includes(..) being called
3. run 'project references' on it
4. check the log

The underlying problem here is that we get so far down the dependency chain while resolving the large collection of files during the all refs search that we end up timing out dependency resolution lookups (expected, we won't wait forever to fill in the graph). When we time out a look up, a null entry gets placed in the worklist (inside Tern) and eventually it tries to run the propagate function on null.

The best fix is to simply check for this, and not try to propagate into a null type.
