Class errors during autoload swallowed

[dmvt]

Because of the autoload functionality, errors in classes get swallowed causing the worker to hang and the message to sit unacked.

reproduce as such:

# app/services/bad_apple.rb
class BadApple
  def incomplete_method_def
    {
  end
end

#app/consumers/sample_consumer.rb
class SampleConsumer
  include Emque::Consuming.consumer

  def message_handler(message)
    BadApple.new
  end
end
