Regression with list items using call() on function with variable args after static args

[davidkpiano]

Sorry for the verbose bug title. This might be related to this: #1604 but it is not the same issue.

TEST:

@function foo($list) {
    @return call(bar, $list);
}

@function bar($list, $args...) {
    @return length($list);
}

test {
  test: foo(1 2 3);
}

EXPECTED: (LibSass 3.2.5 and Ruby Sass 3.4.14)

test {
  test: 3;
}

ACTUAL: (with Node-Sass 3.3.0)

test {
  test: 1;
}

Side note: I'm going to start writing basic unit tests for these in my Sassdash repo since they are all directly related to Sassdash functions, and discovered by their unit tests (~800).

Thanks for the report @davidkpiano I can confirm this is a regression 3.3. We'll be releasing 3.3.1 in the next couple days as regressions are being reported.
