fix #4170: Destructing an undefined property now return 'undefined' instead of the whole store

Should resolve #4170.

Has I described here, the idea is to switch from three arguments (being passed to $$invalidate) to one object so we're able to verify if value is passed with the value undefined or if it isn't passed.

Then we can set $$.ctx[i] as undefined if value is given as undefined instead of the whole store.

CI tests are strangely failing. I can't succeed to reproduce the error.

Thanks, but this is a lot of bytes getting added to the compiled components, which I would say is worse than the arguments.length solution.
