Код модели подтверждения через email теперь является первичным ключом тамблицы

Реализована форма подтверждения email, обмазана тестами
Слегка отрефакторена форма регистрации и авторизации в пользу выноса части логики в общего родителя
Проект зачищен от стандартных тестовых параметров
Пофикшены методы доступа к API
