Subject: [PATCH] Use latest Rust in backend Docker image.

The `pest` crate (a dependency of `comrak`) requires at least Rust 1.23 (https://github.com/pest-parser/pest#usage).

Currently we test crates.io on Travis using latest stable Rust (and newer).
I don't think there's any reason to pin the Docker image to a specific (and outdated) Rust version.
