Title: Final fix for the custom[url] issue

So I was in a bit of a rush earlier today when I submitted that patch, so I didn't catch a pretty big bug that was pointed out to me on one of my [commits](https://github.com/SamJBarney/jQuery-Validation-Engine/commit/3f5cb4f77c78c9bde12335744af4b15124af340c).
Because the delete is being called every time a rule goes through, it causes an error when the array has no elements and is passed to any function called within _getErrorMessage. This fixes that by placing the delete into the if statement so that it only gets called when there is a 'custom' or a 'funcCall'.
Once again, sorry about the mixups. It's been a pretty hectic day.
