Don't force the latest minitest through autotest

If minitest is loaded automatically by autotest the latest version is
used.  This leaves you with no ability to use a previous version.

Since RubyGems loads its preferred minitest through Gem::TestCase we can
let the RubyGems test files take care of it.
Work around single-quote escaping changes

This test fails on ruby 2.x because ' is now escaped to an entity for
HTML and XML output.

Now the escaped or unescaped value is used depending upon the ruby
version.
