fix(animations): provide fake document object in both AoT and JiT mode

The fake document object that is needed for the angular animations
should be provided both when using the static platform and the dynamic
one.

Can be tested with
https://github.com/nativescript/ns-ng-animation-examples.
```bash
// 1
git clone https://github.com/nativescript/ns-ng-animation-examples

// 2
tns run android --bundle --env.aot

// 3
// Navigate to the first example and expect the button to animate to
opacity 0 when tapped.
```

fixes #1163
