Moves migrations tests from railties/test/application/rake_test.rb to railties/test/application/rake/migrations_test.rb

Allow layout fallback when using `layout` method

reversible migration example

Use default charset when we read content type without charset.

Rails will now use your default layout (such as "layouts/application") when you specify a layout with `:only` and `:except` condition, and those conditions fail.

For example, consider this snippet:

    class CarsController
      layout 'single_car', :only => :show
    end

Rails will use 'layouts/single_car' when a request comes in `:show` action, and use 'layouts/application' (or 'layouts/cars', if exists) when a request comes in for any other actions.

Currently if you're do this:

    assert_template :layout => "foo"

Regardless of what layout you were using, the test will always pass. This was broken since the introduction of :layout option in [d9375f3f].

We have a lot of test cases in actionpack/test/controller/layout_test.rb that use this feature. This will make sure that those test cases are not true negative.

A patch has been provided earlier and we have asked for feedback:

    https://gist.github.com/1437939

Except one case, all other cases showed improvements in boot time.

This reverts commit 03d43887.

Reason: I don't think this is absolutely necessary given the
fact that such links won't work in both GitHub and Rails API
at the same time. See links in rails/README.rdoc and rails/Rakefile
for some hackery that needs to be done to get such links work in
both places.
