"Go to definition" in typescript doesn't go to definition, but to type definition

[novellizator]

• VSCode Version: 1.18.1
• OS Version: macOS high Sierra

Steps to Reproduce:

1. open any source in typescript
2. right click on a symbol -> "go to definition"
3. VS Code opens the file with type definitions (mostly from definitelytyped) instead of real symbol definition. = it behaves the same way as "go to type definition"

Reproduces without extensions: Yes
