refresh Gem at the end of teardown.

Browse source 
* lib/rubygems/test_case.rb (teardown): call `Gem::refresh()` at the
  end of `teardown`.
  On parallel test sometimes fails test process. The reason
  is:
  (1) previous tests remains `Gem::Specification@@stubs` value
      which points to temporary directories and the directories
      are removed by `teardown` method of previous test.
  (2) `require 'rubygems/gem_runner'` in `test_gem_gem_runner.rb`
      tries to require test utility file. However, with strange `@@stubs`
      RubyGems tries to load specification from removed directory.
      `StubSpecification#to_spec` returns `nil` and error will occur.
  The solution this patch employs is to refresh all of parameters
  includes `Gem::Specification@@stubs` by `Gem::refresh()`.
