rubygems with multi default gem problem

This issue may affect Ruby committers only. This does not probably affect released ruby.

With development ruby, make install many times. After them, default gems are duplicated when exists updated. And gem with old version in Gemfile does not work well.

Example:

% gem list rdoc

*** LOCAL GEMS ***

rdoc (default: 5.0.0.beta2, default: 4.2.1)
% cat Gemfile
# frozen_string_literal: true
source "https://rubygems.org"

# gem "rails"
gem 'rdoc', '4.2.1'
% cat Gemfile.lock
GEM
  remote: https://rubygems.org/
  specs:
    rdoc (4.2.1)

PLATFORMS
  ruby

DEPENDENCIES
  rdoc (= 4.2.1)

BUNDLED WITH
   1.13.0
% bundle exec ruby -r rdoc -e 'p RDoc::VERSION'
"5.0.0.beta2"
