Reverted and improved TODO:

------
@nupplaphil: There is no easy possibility to add a logger here, that's why there
isn't any yet and instead a placeholder.. This execution point is a critical
state during a testrun, and tbh I'd like to leave here no further logic (yet)
because I spent hours debugging cases, where transactions weren't fully closed
and strange/unpredictable errors occur (sometimes -mainly during debugging other
errors :) ...)
