[jsinterp] Avoid double key lookup for setting new key
...
In order to add a new key to both __objects and __functions dicts on jsinterp.py, it is
necessary to first verify if a key was present and if not, create the key and
assign it to a value.
However, this can be done with a single step using dict setdefault method.
