Fix Elixir root module suggestions

[Goose97]

Fixes #230

[lukaszsamson]

In #230 I was more concerned on why it aliases Elixir. I fixed that on master as well as some other issues in the required_alias.

Regarding your changes I'd like to preserve this module as close to iex as possible. https://github.com/elixir-lang/elixir/blob/5a5947c2d917f519e9a22ec069538106ff9378a0/lib/iex/lib/iex/autocomplete.ex#L563
Can you make a more limited change that only modifies the full name?

Sure, that makes sense.
