Sam Phippen a887c9cbb0 Allow the integration_sesion to be set early on ActionDispatch::Integration::Runner.
In commit fa63448420, @tenderlove changed
the behaviour of the way `integration_session` is set up in this object.
It used to be the case that the first time it was accessed, it was
memoized with nil, however, this means that if it had already been set
it was not replaced. After that commit, it is now always set to `nil` in
the execution of `before_setup`.

In RSpec, users are able to invoke `host!` in `before(:all)` blocks,
which execute well before `before_setup` is ever invoked (which happens
in what is equivalent to a `before(:each)` block, for each test. `host!`
causes the integration session to be set up to correctly change the
host, but after fa63448420 the
`integration_session` gets overwritten, meaning that users lose their
`host!` configuration (see https://github.com/rspec/rspec-rails/issues/1662).

This commit changes the behaviour back to memoizing with `nil`, as
opposed to directly overwriting with `nil`. This causes the correct
behaviour to occur in RSpec, and unless I'm mistaken will also ensure
that users who want to modify their integration sessions early in rails
will also be able to do so.

= Action Pack -- From request to response

Action Pack is a framework for handling and responding to web requests. It
provides mechanisms for *routing* (mapping request URLs to actions), defining
*controllers* that implement actions, and generating responses by rendering
*views*, which are templates of various formats. In short, Action Pack
provides the view and controller layers in the MVC paradigm.

It consists of several modules:

* Action Dispatch, which parses information about the web request, handles
  routing as defined by the user, and does advanced processing related to HTTP
  such as MIME-type negotiation, decoding parameters in POST, PATCH, or PUT bodies,
  handling HTTP caching logic, cookies and sessions.

* Action Controller, which provides a base controller class that can be
  subclassed to implement filters and actions to handle requests. The result
  of an action is typically content generated from views.

With the Ruby on Rails framework, users only directly interface with the
Action Controller module. Necessary Action Dispatch functionality is activated
by default and Action View rendering is implicitly triggered by Action
Controller. However, these modules are designed to function on their own and
can be used outside of Rails.
