fix: Moved extra env files creation, later in the stack (before_restart)

Invoking figaro/dotenv files creation in configure phase, breaks the initial setup of the
application, since the `current` directory is not there yet. Moving it to the `before_restart`
hooks, solves that problem, since the application is properly deployed, and `current` symlink is
created.
