Object.keys and Object.entries should return correct index types

[zakjan]

TypeScript Version: 2.6.1

Code

enum ItemType {
    A = "a",
    B = "b",
}
const obj: { [key in ItemType]: string } = { [ItemType.A]: "x", [ItemType.B]: "y" };

const keys = Object.keys(obj);
const entries = Object.entries(obj);

Expected behavior:
keys should have type ItemType[]
entries should have type [ItemType, string][]

Actual behavior:
keys has type string[]
entries has type [string, string][]
