Bug description

The @tracer.captureMethod() decorator is bound to the decorator not the class its decorating.

export class Lambda implements LambdaInterface {
   @tracer.captureMethod()
   myMethod(){

      //other method is undefined as "this" is no longer the Lambda class
      this.otherMethod()
   }

   otherMethod(){}
}

Expected Behavior

this.otherMethod() should call the this.otherMethod() in the same class

Current Behavior

this.otherMethod() is undefined

Possible Solution

see #1026
the @tracer.captureLambdaHandler() decorator already does this

Steps to Reproduce

1. create a class with two or methods in it
2. add the decorator @tracer.captureMethod() to one or more of the function
3. call another method or prop in the decorated method
4. the method or prop will be undefined

Environment

• Powertools version used: 1.0.2
• Packaging format (Layers, npm):
• AWS Lambda function runtime:
• Debugging logs:
