Wrong version of release is started

[rjanja]

This is a placeholder to track an open issue at bitwalker/distillery#693 about Distillery not updating var/start_erl.data, so the incorrect version of the application is started.

A workaround is to remove this file post-deploy.

# https://github.com/bitwalker/distillery/issues/693
task :clear_start_erl do
  remote :app do
    "rm -f var/start_erl.data"
  end
end

after_task(:deploy, :clear_start_erl)
