Issue

The whitespace on the LHS of a destructuring assignment is not formatted.

Steps to Reproduce:

1. Add the following to a typescript file:

const {NoSpaces} = { NoSpaces: 1 }
const { WithSpaces } = { WithSpaces: 1 }
const {OneSpace } = { OneSpace: 1 };

2. Format the document.

Expected

I would expect the whitespace on the LHS of the assignment to be consistent. I would expect either:

const {NoSpaces} = { NoSpaces: 1 }
const {WithSpaces} = { WithSpaces: 1 }
const {OneSpace} = { OneSpace: 1 };

or

const { NoSpaces } = { NoSpaces: 1 }
const { WithSpaces } = { WithSpaces: 1 }
const { OneSpace } = { OneSpace: 1 };

Actual Output

Whitespace of the LHS is inconsistent:

const {NoSpaces} = { NoSpaces: 1 }
const { WithSpaces } = { WithSpaces: 1 }
const {OneSpace } = { OneSpace: 1 };
