Make test function unique for Report Portal

[trepel]

Overview

Report Portal does not handle test functions with the same name well. It deals with them as if they are separate runs of the same test function

To fix this we must either rename our test functions so that they have unique names across the test suite or update the uploading to Report Portal so that the whole path is used rather than just test function name. Not sure how difficult/feasible the latter is but it is a cleaner approach.
