Version

3.1.1

Reproduction link

https://github.com/millimoose/vue-tslint-microsoft-contrib-bug

Node and OS info

Node 9.7.1 / npm 6.4.1

Steps to reproduce

1. Clone and npm install in that repro
2. npm run lint --no-fix

What is expected?

Typed TSLint rules should only be run on files that have a corresponding entry in the backing TypeScript program. Some operations run on nodes in the files by TSLint rules query the program for type information only available on those files.

What is actually happening?

The Vue CLI is patching the program's getSourceFile to return a manually created file from ts.createSourceFile for Vue files (per isVueFile).

Untyped rules will work fine with this, but some typed rules will throw. For example, no-unsafe-any crashes: palantir/tslint#4273

This is a more general case of #2712 as originally reported by @millimoose. The bug investigation trail went from there to TSLint to TypeScript and back to here, amusingly.
