Fixes #3179: removed duplicate validation rules from User model in advanced app, removed User::create()

This reverts commit 2bb6f135.

Fixes #2458: Added missing validaton to advanced app forms, separated validation from email sending errors for contact form

* Added 'return' to goHome() calls in actions
* Changed $_POST to Yii::$app->request->post()

Added in an isset check because if you set a flash type that is not in our expected index it will throw a undefined index error
