Description: Fix tests with ruby2.3
 This test use TrueClass and your public methods to generate a TestTrueClass.
 From ruby2.2 to ruby2.3 have some changes in public methods, in ruby2.3 have
 '===' (equals3) method and ruby2.2 do not have it. So the test is removed,
 because it will fail in one of the ruby version at least.
