`UnknownElementException` error with Nest v8 #35

Closed tahubu closed 3 years ago

During Nest application bootstrap, I get this error:

UnknownElementException [Error]: Nest could not find MyListener element (this provider does not exist in the current context)

From version 8, Nest uses class reference instead of class constructor name as injection token, but @team-supercharge/nest-amqp library supports only class constructor names. Here is the commit about the modification.
