Fluent::Logger::TestLogger.open returns a Fluent::Logger::FluentLogger instance

[eagletmt]

At fluent-logger 0.4.7, Fluent::Logger::TestLogger.open returns a Fluent::Logger::TestLogger instance.
At fluent-logger 0.4.8, it returns a Fluent::Logger::FluentLogger instance.
It's caused by 2068b44 discussed in #10.

Is it an intended change?

Hmm. We seem to do same check in Fluent::Logger::LoggerBase.open like Fluent::Logger.open.

    if !args.first.is_a?(Class) || !args.first.ancestors.include?(LoggerBase)
      args.unshift(self)
    end

class LoggerBase
  def self.open(*args, &block)
    Fluent::Logger.open(*args, &block)
  end

I think that it is the problem which stopped including self in an argument by change of #16.
If it is problem, I can write a patch. What do you think?

@daic-h If you have more better solution to fix this and #16, patches are welcome!
