use .call instead of .apply

In javascript `Function.prototype.apply()` expects an array as second argument. However, at the moment the error object instead of an array is passed to the `apply` method. So in this case, `Function.prototype.call()` makes for sense than `apply()`, because then you can pass arguments directly.
