[fixed] Issue where label assertion returns a false negative when label is inside a child Component (fixes #44)

[added] Tests to ensure anchors with a tabIndex but without an href require an ARIA button role (fixes #45)
[added] selection and option to the list of interactive elements that require labels
[removed] getFailures() method since all failures are now logged asynchronously
