elixir deps are not added to the lock file

[benoitc]

I was trying a modified version of the demo:

but the lock file is not updated when doing rebar3 compile, only httpoison is added to it but none of the deps are fetched via mix. More over running the application return the following:

So it seems that it doesn't find hackney.
