Make the ignored tests to be decorated with the Ignore category as well

[wsklorz]

The goal here is to make the ignored tests to be decorated with the Ignore category as well as it is decorated appropriately for each test framework. This allows to set up freely the test filter for each runner. The issue is that the ignored tests are inadequately factored in the math of tests pass percentage, which makes them included in/as the not-passed factor. Microsoft is not going to change this behavior in the classic release pipelines so that is a must-have workaround in order to achieve the proper statistics of the BDD tests.
