Overwriting when using shortcuts

[sadlowskij]

I have found unexpected behavior with different results when using shortcuts and without using shortcuts, see:

const good = FileBuilder.normalizeFileObject({
  'a/': {
    'a1.json': {
      jsonKey: 'jsonValue',
    },
    'a2.json': {
      jsonKey: 'jsonValue',
    },
  },
});
console.log(good);
const bad = FileBuilder.normalizeFileObject({
  'a/a1.json': {
    jsonKey: 'jsonValue',
  },
  'a/a2.json': {
    jsonKey: 'jsonValue',
  },
});
console.log(bad);

This leads to this log:

{
  'a/': {
    'a1.json': { jsonKey: 'jsonValue' },
    'a2.json': { jsonKey: 'jsonValue' }
  }
}
{ 'a/': { 'a2.json': { jsonKey: 'jsonValue' } } }

I think the problematic behavior occurs in this line, where the previous value for the path is being overwritten.
