fixes "Cannot call method 'split' of null" error

Was getting this error:

ERROR [karma]: [TypeError: Cannot call method 'split' of null]_-_-_-_-_-_-_-_-_-_,------,

on this test:

var Utility = {};
    Utility.capitalize = function(str){
      if(typeof str !== 'string'){return str;}
      return str.charAt(0).toUpperCase() + str.slice(1);
    };

var allTypes = {
  string : 'string'
  , caps : 'String'
  , camel: 'aStringOfStuff'
  , spaces: 'a string of stuff'
  , specialCharacters : '!@#$%^&*()_=-`{}|\\][;\':"<>?/.,¢∞§ªº–≠'
  , fn : function(){}
  , factory : function(){ return function(){} }()
  , num : 123
  , bool : true
  , boolf : false
  , boolo : 1
  , boolz : 0
  , nl : null
  , undf : ''
  , obj : {}
  , arr : []
};

describe('The Utility Service', function() {
  it ('is defined', function () {
    expect (Utility).toExist ();
  });
  describe ("Utility has a", function () {
    it ('capitalize function which will capitalize the first letter', function () {
      var result = Utility.capitalize (allTypes.caps);

      expect (result).toBe (allTypes.string);
      console.log (allTypes.string);

      expect (result).toBe (allTypes.string);
      expect (result).toBe (allTypes.caps);
      expect (result).not.toBe (allTypes.string);
    });
  });
});

solution was to check for null before attempting split.

Awesome, thanks for the contribution. I'll get it to npm ASAP!
