cck field views arguments is not transmited correctly and fix

when you set view arguments to be passed to the selected view to display the nodes, the arguments are handled incorrectly in code leading to them being lost, patch included below

the view arguments are a comma separated string of arguments, the string is exploded into an array which is then concatenated to a string leading to the string having the value "Array"
as far as ive learned, the view_args should be an array of arguments, i am not sure why passing a string as an array's element [0] doesnt work in my case, if i just pass the string along, it works, but you wont be able to send multiple arguments and this should be FIXED if possible, i dont have time to dig on this right now so i would appreciate any advice
