BUG: currentLoop.name broken (online/psychoJS) when nested loops are used

[RebeccaHirst]

When nested loops are used the attribute currentLoop.name is correct locally but not online.

Minimal demo here: https://run.pavlovia.org/lpxrh6/loopname_bug_demo/
Repository for demo: https://gitlab.pavlovia.org/lpxrh6/loopname_bug_demo/

Expected behaviour:
When currentLoop.name is called it should return the name of the loop in which the current routine is located. i.e. in the below the correct currentLoop.name for the routine "trial" should be "trials" and in the routine "feedback" the correct loopname is "fb_loop". Locally, this works, but online as soon as one iteration of fb_loop has been completed the currentLoop.name in the "trial" routine becomes "fb_loop".
