Renaming class name switches up order in object literal shorthand

For the JS:

class A { }
module.export = { A };

1. Rename A in class A {}

Expected behavior:

class B { }
module.export = { A: B };

Actual behavior:

class B { }
module.export = { B: A };

The order in the exported object literal is swapped so we end up referencing A which no longer exists
