bug fix about 'ApplicationName'

It is also the content of the above issue.
This is a problem that occurred when using amqp-ts in electron.

import * as Amqp from "amqp-ts";

If the content is declared in app.ts and used, the application will refer to amqp-ts immediately at runtime,
This application will be assigned an ApplicationName. At this time, if the process.env.AMQPTS_APPLICATIONNAME value of the process environment is not assigned, the length of process.argv is not present, or is less than 1, an error inevitably occurs.

Since ApplicationName is not a global variable, we know that it is only used in the consumerQueueName method.

ApplicationName has a valid value only when the application is started and the startConsumer is executed as needed.

Therefore, modify to allocate AppliacationName when consumerQueueName method is called.
