[Bug] Dataset treats array of array differently than array of object

### Version

5.4.1

### Link to Minimal Reproduction

https://codepen.io/tobibe/pen/VwBEjvr

### Steps to Reproduce

create a line-chart option with dataset array of arrays and the same data with array of objects and use in both the series-option seriesLayoutBy: 'row'

### Current Behavior

with dataset as array of objects, it seems to ignore the series-option seriesLayoutBy: 'row'

behaves right:
```
dataset: {
source: [
['product', '2015', '2016', '2017'],
['Matcha Latte', 43.3, 85.8, 93.7],
['Milk Tea', 83.1, 73.4, 55.1],
['Cheese Cocoa', 86.4, 65.2, 82.5],
['Walnut Brownie', 72.4, 53.9, 39.1]
]
},
```

behaves like without seriesLayoutBy: 'row':
```
dataset: {
dimensions: ['product', '2015', '2016', '2017'],
source: [
{ product: 'Matcha Latte', '2015': 43.3, '2016': 85.8, '2017': 93.7 },
{ product: 'Milk Tea', '2015': 83.1, '2016': 73.4, '2017': 55.1 },
{ product: 'Cheese Cocoa', '2015': 86.4, '2016': 65.2, '2017': 82.5 },
{ product: 'Walnut Brownie', '2015': 72.4, '2016': 53.9, '2017': 39.1 }
],
},
```


### Expected Behavior

same behavior in dataset with array of array as array of object

### Environment

```markdown
- OS: Windows
- Browser: Firefox/Chrome
- Framework: Angular
```
