LibJS: Allow function calls with missing arguments
...
We were interpreting "undefined" as a variable lookup failure in some
cases and throwing a ReferenceError exception instead of treating it
as the valid value "undefined".
This patch wraps the result of variable lookup in Optional<>, which
allows us to only throw ReferenceError when lookup actually fails.

LibJS: Rename some tests
...
"feature-basic" is a bit more logical than having a ton of
"basic-feature" (when it comes to the visual overview of it all.)
