Fixed bug in checkArgs of jsdebug showing wrong error.

Now optional arguments get skipped when there are less arguments than
possible params.

Example of the previous behaviour:

Imagine a signature like that: testFunction([bool1: bool], bool2: bool,
someString: String);

And a call like this: ``testFunction(true, "test");``

We would have printed: "Arguments mismatch: testFunction([bool1], bool2,
someString) - String specified where bool expected ..."
with bool2 marked red.

Now we're skipping the first argument and print nothing.
