[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.

Philipp Hagemeister 3eff81fbf7 [jsinterp] Disable comment support
We need a proper lexer to be able to understand YouTube's code, which contains /* inside of strings.
For now it's sufficient to just disable comment support altogether.

Fixes #4976, fixes #4979, fixes #4980, fixes #4981, fixes #4982.
Closes #4977.
