Auto loading of YML config for tasks with dependencies

[nithinphilips]

I ran into an issue with auto loading of YML config files. Here's a patch that fixes the problem.

Background:

My Rakefile had a task definition like this:

rapc :supertask => [:subtask1, :subtask2] do |r|
    ...
end

rapc is a custom task.

When I tried to put settings in the yml file, I noticed that they were never loaded. While investigating the problem I realized that the task_name parameter passed into the load_config_by_task_name method is, in case of a task definition like the one above, a Hash, rather than a Symbol. The following patch ensures that the correct yml config file will be loaded in this case.
