Edouard CHIN 0cdeee428e Fix AJ wrong deprecation message on after_callbacks_if_terminated:
- ### Problem

  In some cirumstances, the deprecation message to warn that AJ won't
  run `after_(enqueue/perform)` callbacks when the chain is halted
  by a `throw(:abort)` will be thrown even though no `throw(:abort)`
  was thrown.

  ```ruby
    run_callback(:foo) do
      ...
    end
  ```

  There is two possible way for the callback body to not be executed:

  1) `before` callback throw a `abort`
  2) `before` callback raises an error which is rescued by an
     around callback (See associated test in this commit for
     an example)

  When 2) happen we don't want to output a deprecation message,
  because what the message says isn't true and doesn't apply.

  ### Solution

  In order to differentiate between 1) and 2), I have added
  a `halted_callback_hook` which is called by ActiveSupport callback
  whenever the callback chain is halted.
