fixed the separator taken as a vaarg

fixed the separator taken as a vaarg problem so now : 
`Log.i("Response data is", responseData, "and code is", responseHttpCode);`

*WILL* log this : 
`"Response data is [value of responseData] and code is [value of responseHttpCode]"`

Why should the separator be in lowercase?
