Ignores present unicorn configuration files when daemonizing

[michaelfranzl]

Since about 10 years, rack is already daemonizing the process (using Process.daemon) when options[:daemonize] is set (e.g. when the -d flag is set in rails server), just before calling Rack::Handler::Unicorn.run (which unicorn-rails implements). Ruby's core Process.daemon changes the working directory to root ("/"). This is why this line will never find the configuration file:

unicorn-rails/lib/unicorn_rails.rb

Line 19 in cb99f63

elsif ::File.exist?("config/unicorn.rb")

Have absolutely the same problem.
