[tests] Migrate off fest-assert to assertj

fest-assert 2 once was assertj.  The authors differed in direction and the framework split.  fest-assert itself is long dead.  Version 2 never made release as a result and the migration as it were is incredibly easy as seen here and at least in one test set makes more logical sense.
