Elixir projects in RubyMine don't use Elixir/Erlang SDK libraries

[mirrec]

Describe the bug

• IDE does not use Elixir/Erlang SDK from settings at all. What I mean by that:
  • I cannot see it in project structure,
  • CMD+click / "go to Declaration or Usage" does not work
  • autocomplete does not work
  • All of mentioned above work fine with local modules or dependencies.
• Surprisingly, I am able to compile and run tests from IDE.
• I have a feeling that this problem was introduced when I updated RubyMine to the last version, but I can't tell for sure.
• I have this issue in all of my existing / newly created elixir project.

To Reproduce

1. Download and install my very basic elixir project repo https://github.com/mirrec/sdk-problem-intellij-elixir
2. (Maybe you need a RubyMine)

Expected behavior
I expect IDE to load and work with Elixir/Erlang SDK from settings.

Screenshots

1. project tree does not contain any path to elixir/erlang sdk

2. preferences looks good to me

3. autocomplete does not work for elixir/erlang sdk

4. tests in IDE work fine

@mirrec Hey there, try following this advice: #1789

I have discovered it recently and i can verify that i always thought autocomplete is broken, but it is in fact not, it is just painfully slow to load the first time.
