fix(animations): provide fake document object in both AoT and JiT mode (#1164)

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
