Audience parameter is ignored for app switch transactions

[joeycarmello]

The following method does not accept an audience parameter:

 - (void)sendAppSwitchTransactionTo:(NSString *)recipientHandle
               transactionType:(VENTransactionType)type
                        amount:(NSUInteger)amount
                          note:(NSString *)note
             completionHandler:(VENTransactionCompletionHandler)completionHandler

This method is called internally by:

 - (void)sendRequestTo:(NSString *)recipientHandle
                         amount:(NSUInteger)amount
                           note:(NSString *)note
                       audience:(VENTransactionAudience)audience
              completionHandler:(VENTransactionCompletionHandler)handler;
