uncover bug with minitest + shoulda-context + shoulda-matchers

[anmarchenko]

Fixes #130

What does this PR do?

There is a bug with minitest tests when using shoulda-context together with shoulda-matchers for tests like:

class CalculatorTest < Minitest::Test
  context "a calculator" do
    should delegate_method(:substract).to(:substractor)
  end
end

In this case test should delegate_method does not have an associated test_suite_id and is being skipped because it is not valid for test suite level visibility.
