Completions are low-quality for UMD modules without typings

For example, reference oidc-client.js from the corresponding npm package, instantiate an Oidc.UserManager, and dot into the resulting object.

Expected: properties of Oidc.UserManager are offered
Actual: identifiers appearing in file are offered (i.e. min-bar experience).

There are two builds of that library -- one that assumes you're using a package manager (in ~/lib), and another that doesn't (in ~/dist). The samples I used to show to @amcasey were not (so the ones in ~/dist).
