Hi

I've been migrating my umbrella project to Erlang 20 and Elixir 1.5.0. I upgraded confrom from 2.1.2 to 2.5.0 to get latest fixes for Elixir 1.5.0 but now I have an error from conform plugin during release generation with distillery.

==> Assembling release..
==> Building release conform_umbrella_test:0.1.0 using environment dev
==> Plugin failed: Invalid schema at line 74: syntax error before: [<<"second_app.another_var">>].

I looked at the schema by dumping input argument for Conform.Schema.parse!/1 and got this in transform section:

  transforms: [
    "first_app.my_var": #Function<6.99386804/1 in :erl_eval.expr/5>,
    "second_app.another_var": #Function<6.99386804/1 in :erl_eval.expr/5> # <-- line 74
  ],

Full schema from this step can be seen here.

I also checked non-umbrella app release generation and it works fine with similar case (using transforms). Instead of inspected anonymous functions in transform section (like in example above), there were actual functions text, which I assume is how it should be.

I've made a demo app which reproduces umbrella case https://github.com/tenkai9/conform_umbrella_test
