Subject: [PATCH] Update .travis.yaml to include the 3 latest elixir versions
 (#414)

* Update .travis.yaml to include the 3 latest elixir versions

* Avoid using `super` in GenServer callbacks

Using `super` in GenServer callbacks was deprecated in elixir 1.7,
to avoid compilation warnings, this commit replaces all calls to
`super` with an explicit return
