Fixed CB-2620: console.log prints only the first argument on Xcode console

See: https://issues.apache.org/jira/browse/CB-2620

Running:
`console.log('Hello', 'world', {hello: 'world'}, [1,2,3], 1, 2, true, undefined, null);`

On various browsers:

//Output Chrome: 
`Hello world Object {hello: "world"} [1, 2, 3] 1 2 true undefined null`

//Output Firefox:
`Hello world Object { hello= "world" } [ 1 , 2 , 3 ] 1 2 true undefined null`

//Output Safari: 
`Hello world Object [1, 2, 3] 1 2 true undefined null`

However, on Xcode's console, the output before the fix is:
`[LOG] Hello`

After the fix:
`[LOG] Hello world {"hello":"world"} [1,2,3] 1 2 true undefined null`
