Confusing ... suggestion showing in ts files on arrow functions

[mjbvz]

Issue Type: Bug

repo

1. Using TS 3.2
2. Open a ts file:

const a = (x) => x; 

Bug
Notice the ... under x. When you move the cursor over the ..., we offer the convert to braces / remove braces refactoring

This behavior is really confusing. Accepting these refactors will not get rid of the ..., which is actually an infer type suggestion

Root cause microsoft/TypeScript#28702 but I'm just going to disable these suggestions entirely on broken TS versions
