Rename field to a name with dash does not transform the field with quotes.

<!-- Please try to reproduce the issue with `typescript@next`. It may have already been fixed. --> **TypeScript Version:** 3.5.0-dev.20190412 <!-- Search terms you tried before logging this (so others can find this issue more easily) --> **Search Terms:** hyphen refactor, dash rename **Code** ```ts interface TestObject { test:string } const instance: TestObject = { test: "hello" }; console.log(instance.test); ``` Rename "test" to a variable with a hyphen, e.g "te-st" **Expected behavior:** Code is refactored to use quotes: ```ts interface TestObject { "te-st":string } const instance: TestObject = { "te-st": "hello" }; console.log(instance["te-st"]); ``` **Actual behavior:** Refactor replaces the variable as given, producing invalid code ```ts interface TestObject { te-st:string } const instance: TestObject = { te-st: "hello" }; console.log(instance.te-st); ``` **Playground Link:** Replacing all occurrences in the playground also includes all Test matches, so I tested this in vscode **Related Issues:** none I could find
