Duplicated load path

[junaruga]

When we would run test, the load path "lib:bin:test:." is loaded by Hoe test default settings.

https://github.com/seattlerb/hoe/blob/master/lib/hoe.rb#L106

So, I think we do not need to set load path in test/testhelp.rb again.
How do you think?

$ bundle exec rake test
...
/usr/local/ruby-2.3.1/bin/ruby -w -Ilib:bin:test:. -e 'require "rubygems"; require "minitest/autorun"; require "test/test_thread_pool.rb"; require "test/test_puma_server.rb"; require "test/test_app_status.rb"; require "test/test_rack_server.rb"; require "test/test_minissl.rb"; require "test/test_tcp_logger.rb"; require "test/test_unix_socket.rb"; require "test/test_tcp_rack.rb"; require "test/test_null_io.rb"; require "test/test_http10.rb"; require "test/test_rack_handler.rb"; require "test/test_persistent.rb"; require "test/test_ws.rb"; require "test/test_puma_server_ssl.rb"; require "test/test_config.rb"; require "test/test_iobuffer.rb"; require "test/test_integration.rb"; require "test/test_cli.rb"; require "test/test_http11.rb"' --
...

Below tests were also passed.

$ bundle exec rake test
$ bundle exec rake test:integration
