railites_order method, introduced in 40b19e0, had a bug that was causing loading application instance twice in initializers if railties_order already included application instance. So for example railties_order = [Foo::Engine, :main_app, Bar::Engine] would result in such railties array: [MyApp::Application, Foo::Engine, MyAppApplication, Bar::Engine] In order to fix it, we need to check for existence of application in both railties_order and railties arrays.

In development mode, dependencies are loaded dynamically at runtime, using `const_missing`. Because of that, when one of the constants is already loaded and `const_missing` is not triggered, user can end up with unexpected results. Given such file in an Engine: ```ruby module Blog class PostsController < ApplicationController end end ``` If you load it first, before loading any application files, it will correctly load `Blog::ApplicationController`, because second line will hit `const_missing`. However if you load `ApplicationController` first, the constant will be loaded already, `const_missing` hook will not be fired and in result `PostsController` will inherit from `ApplicationController` instead of `Blog::ApplicationController`. Since it can't be fixed in `AS::Dependencies`, the easiest fix is to just explicitly load application controller. closes #6413

In case `source_roout` is not set, `default_source_root` is used, which includes also `templates` directory. If there is no `templates` directory, `default_source_root` is not available and USAGE will not be displayed. USAGE should be also checked based on default directory excluding `templates`.
