Fix compilation error:

Does this also work on previous Erlang versions?

This is related only tests so it only fix compilation error under R17

Regarding tests I have same errors with R17/R16 with patch and without too:

folsom_erlang_checks: create_delete_metrics (create and delete tests)...*failed*
in function ets:member/2
  called as member(folsom,counter)
