Fix warnings

[thiamsantos]

Motivation

In elixir 1.11 I'm getting the following compile warnings during rustler compilation.

==> rustler
Compiling 5 files (.ex)
warning: EEx.eval_string/3 defined in application :eex is used by the current application but the current application does not directly depend on :eex. To fix this, you must
do one of:

  1. If :eex is part of Erlang/Elixir, you must include it under :extra_applications inside "def application" in your mix.exs

  2. If :eex is a dependency, make sure it is listed under "def deps" in your mix.exs

  3. In case you don't want to add a requirement to :eex, you may optionally skip this warning by adding [xref: [exclude: EEx]] to your "def project" in mix.exs

  lib/mix/tasks/rustler.new.ex:79: Mix.Tasks.Rustler.New.copy_from/3

warning: Toml.decode!/1 defined in application :toml is used by the current application but the current application does not directly depend on :toml. To fix this, you must d
o one of:

  1. If :toml is part of Erlang/Elixir, you must include it under :extra_applications inside "def application" in your mix.exs

  2. If :toml is a dependency, make sure it is listed under "def deps" in your mix.exs

  3. In case you don't want to add a requirement to :toml, you may optionally skip this warning by adding [xref: [exclude: Toml]] to your "def project" in mix.exs

  lib/mix/tasks/compile.rustler.ex:177: Mix.Tasks.Compile.Rustler.check_crate_env/1

Proposed Solution

• Add logger and eex to the extra_applications option
• Add elixir 1.11 to CI (the new version is not available at https://www.erlang-solutions.com/resources/download.html)

Thank you for the pull request! Can you re-add Elixir v1.11 to CI? It should be available by now I think (here)

@evnu Sure, I force pushed the CI for 1.11
