build(docs): fix description comments sometimes empty

[devversion]

Follow-up commit for 4879dc4 since angular/dgeni-packages#270 has been merged and published.

---

Disables concatenation of multiple leading comments for a TypeScript node. Since all shipped source files have a license banner at top, the license banner comment would be incorrectly considered as "comment" for the first TypeScript node of a given file. Since there are various files in the Material project where the first node of a source file is exported and should only use the first leading comment, we need to disable comment concatenation.

See for example: https://github.com/angular/material2/blob/master/src/cdk/coercion/boolean-property.ts

@jelbourn Rebased. I'm adding merge ready. Let me know if there is anything that we should wait on.

@devversion travis is red across the board

Seems to be because of postinstall trying to check the typings of @angular-devkit/core (this now appears because I've updated the package-lock and locally I got this as an explicit error)

See: https://unpkg.com/@angular-devkit/[email protected]/src/virtual-fs/host/test.d.ts

@jelbourn Fixed. For this PR, I'm just updating the package-lock to reflect the dgeni-packages update.

As mentioned in the comment above, previously I updated all packages and something broke. This is something that should be fixed separately.
