Prepend the transaction around_action so libraries with controllers can alter the value

[drcapulet]

For gems that define controllers, the following code:

initializer 'raven.action_controller' do
  ActiveSupport.on_load :action_controller do
    ...
    include Raven::Rails::ControllerTransaction
    ...
  end
end

Runs after the controller (and any related *_actions) are defined and prevents that controller from being able to change the transaction. By prepending the around_action, the transaction is correctly set before any code in that controller runs and allows that controller to change the transaction.
