escript fails to start with "could not find application file: logger.app"

[ivan]

After 75e2ee0, if you mix escript.build and have a

 def application do
   # Specify extra applications you'll use from Erlang/Elixir
   [extra_applications: [:logger]]
 end

in your mix.exs, the compiled escript errors out with:

# ./escript_demo
Could not start application logger: could not find application file: logger.app

This is reproducible with an empty project created by mix new (just add an escript: escript() listing a main_module.)

Removing the def application makes the escript work, at least for escripts that don't need the logger.

Fixed in #5534.
