Description

In cordova.js, callbackFromNative method, when handles the exception, it
only logs the callbackid and error message, but does not log the error
callstack. Usually the callstack is quite useful to find what causes the
exception, so just wonder what is the reason to not include it in the error
console log.

If it is fine to include the call stack information in the console log, I
would like to submit a pull request for the change.

   /**
      * Called by native code when returning the result from an action.
      */
     callbackFromNative: function(callbackId, isSuccess, status, args, keepCallback) {
         try {
             var callback = cordova.callbacks[callbackId];
             if (callback) {
                 if (isSuccess && status == cordova.callbackStatus.OK) {
                     callback.success && callback.success.apply(null, args);
                 } else if (!isSuccess) {
                     callback.fail && callback.fail.apply(null, args);
                 }
                 /*
                 else
                     Note, this case is intentionally not caught.
                     this can happen if isSuccess is true, but callbackStatus is NO_RESULT
                     which is used to remove a callback from the list without calling the callbacks
                     typically keepCallback is false in this case
                 */
                 // Clear callback if not expecting any more results
                 if (!keepCallback) {
                     delete cordova.callbacks[callbackId];
                 }
             }
         }
         catch (err) {
             var msg = "Error in " + (isSuccess ? "Success" : "Error") + " callbackId: " + callbackId + " : " + err;
             console && console.log && console.log(msg);
             cordova.fireWindowEvent("cordovacallbackerror", { 'message': msg });
             throw err;
         }
