Issue: Data sets can't be defined with array in version 1.1.2 but can be in version 1.0.1
#### What are you trying to achieve?
I hope data sets can be defined with array...
#### What do you get instead?

Pull request description: [Data Driven Tests] Accept plain arrays (regression fix)
### Highlights

* Support plain arrays again in the Data Driven Tests. (Fixes #920)

### Background

Plain arrays worked in v1.0.1 but broke some time later.

The docs (advanced.md) already mention that `Data sets can also be defined with array, generator, or a function.`. So no need to update them.

Here is the example which now works again.

```js
Feature('ehm');

// Case 1: Allow plain arrays
Data(['1', '2', '3']).Scenario('data table test array', (I, current) => {
    I.amOnPage('/');
    console.log(current);
});
```
