fix tests for rspec 3

* rewrite use of "its" as regular "it" assertions as "its" is no longer part of rspec-core
* change "be_true" assertions to use "be true" since True no longer responds to true?

Convert specs to RSpec 3.1.7 syntax with Transpec

This conversion is done by Transpec 2.3.8 with the following command:
    transpec

* 1 conversion
    from: obj.should
      to: expect(obj).to

* 1 conversion
    from: obj.stub(:message)
      to: allow(obj).to receive(:message)
