Assign the `primaryHost` prior to initializing the registered Android plugins.

Address a regression introduced in https://github.com/godotengine/godot/pull/102866.
The proper behavior for Android plugins is to use `getContext` instead of `getActivity`, but since not all plugins follow this pattern, this fix provides backward compat to avoid breaking the plugins that don't.
