Description
An empty function call is not the same, as calling a function with an undefined variable.
If we check against !arguments.length instead of undefined, we can tell apart these situations.
OLD:
.removeClass() - removes all classes, as expected
.removeClass(undefined) - also removes all classes, which is wrong in my eyes
Fix:
.removeClass(undefined) - removes nothing, like null, false and "" do

PS:
I noticed this while calling element.removeClass(someObject.someVar);
where the object was defined, but someVar was undefined, so this is a pretty common situation, I think.

Fix #12411, .removeClass(undefined) is a chaining no-op. Close gh-913.
.removeClass() removes all classes, as documented
.removeClass(window.nonExistentVariable) removes nothing
