fix array cast (microsoft#974)

Fixes microsoft#973

The fix can best be illustrated by running this code:

```powershell
@('[]' | ConvertFrom-Json).Count
@('[{"a":"1"}]' | ConvertFrom-Json).Count
@('[{"a":"1"},{"b":"2"}]' | ConvertFrom-Json).Count
```

Returns: 1, 1, 1
Expected: 0,1,2

Where this:

```powershell
('[]' | ConvertFrom-Json).Count
('[{"a":"1"}]' | ConvertFrom-Json).Count
('[{"a":"1"},{"b":"2"}]' | ConvertFrom-Json).Count
```

Returns: 0,1,2 as expected

 ### Build modes
 AL-Go ships with Default, Translated and Clean mode out of the box. Now you can also define custom build modes in addition to the ones shipped with AL-Go. This allows you to define your own build modes, which can be used to build your apps in different ways. By default, a custom build mode will build the apps similarly to the Default mode but this behavior can be overridden in e.g. script overrides in your repository.
