Summary14401: If options for "token based answer persistance" and "Allow multiple responses..." are enabled, "uses left" is not decreased

If at a closed survey the options for "token based answer persistance" and "Allow multiple responses or update responses with one token:" are enabled, the uses left value doesn't get decreased on submit. I think this was the case at previous versions like 2.6 LTS. It can cause the following problem: If a user now changes those two settings by switching them off, all participants can participate once more - since uses left is 1 on survey start - so we end up with 2 data sets for each participant.

Steps To Reproduce
  1. Use a non-anonymous survey with "token based answer persistance" and "Allow multiple responses..." enabled.
  2. Add a test user.
  3. Add a data set for that user.
  4. Change those two settings by switching them off.
  5. Take the survey with your test user again and submit another response.
  6. You end up with two response data sets for the same user though it is a closed survey with "uses left" being set to 1 as default value.

I think « update responses with one token» (with «token based answer persistance») don't use useleft

I think in 2.6lts : use left was decremented in all situation.
