BHV-5143: modify setActive parameter in ListActions.js

BHV-5143: ListActionsSample: open/close message is not fired consistently

### Analsys and Solution
After moved 'setActive' line into openChanged function, parameter should be changed. Because, after setOpen call, 'open' property is already changed. So I modify setActive parameter in openChanged function.
