In case a new administrator is created by a non-superuser and no permission is set directly on creation, `permissions` is not initialized correctly. Thus, when the non-superuser tries to acceess `$this->model->permissions` it is not populated with an empty array as expected.
I have actually no clue why it does work for superusers however, as they should certainly experience the same issue, but this is not the case.
Fixes#3315 by moving the manipulation of the filter widget scopes to the controller event method instead of before any part of the controller constructor method is run.
This enables arbitrary form contexts to be defined to override the default values when using a form with custom contexts. I.e. `$this->update($id, 'mycustomcontext');` will load the form definition from `mycustomcontext[form]` instead of `update[form]`
This aligns better with the relation principal "parent saves child" / "child cannot save parent" and is more conducive to the natural workflow of a coder, ie
// Relation first
$gallery = new Gallery;
$gallery->save();
// Primary model last
$post = new Post;
$post->gallery = $gallery;
$post->save();

Converts a field name in the form of `model_json_attribute[subproperty]` to the dot syntax version used by validation rules `model_json_attribute.subproperty` for more accurate checking of the validation rules in the form widget.
This fixes#2613 by reloading the form widgets with the modified data after `model.filterFields`. **NOTE**: `$this->processExistingItems()` isn't simply just moved to `prepareVars()` because that messes up the adding new repeater item functionality by repeating the content from the fields for the last item in that group that already exists on the repeater.
