Bug: reuseDuration has no effect

Hello,

I was trying to use the `reuseDuration` option, but it has no effect. (ie: by launching the same `index.js` twice in a row)

Does the process that has requested the touchID needs to be kept alive to reuse the touchID?

Thanks in advance!

Start by reproducing the behavior with the same index.js launched twice in a row, then trace how reuseDuration and the Touch ID request are handled. Confirm whether the requesting process must remain alive, and consider the issue done when repeated launches either reuse authentication as intended or document the limitation with a regression test.
