junit-formatter broken on Debian 7

[mzemel]

I can use this application just fine in my test suite when running an Elixir app on Mac, however when I try to do mix test in a docker container, I get:

Finished in 0.3 seconds (0.2s on load, 0.1s on tests)
13 tests, 0 failures

This can be solved with sudo apt-get install erlang-xmerl

Nice! I will probably add the dependency on xmerl application.

Thanks for reporting!
