fix(tracer): capture method throws errors correctly

[dreamorosi]

Description of your changes

As reported by @saragerion, the Tracer method captureMethod was incorrectly catching errors thrown within the body/scope of a decorated Class method defined by users. This is not a desired behaviour as the utility should not catch customers' errors but should simply run the logic defined in the decorator function and then throw the error along for customers to handle/throw in their code.

We had this behaviour on the radar as shown by the TODO comment present in that part of the code (see diff) but up until now we hadn't noticed / it wasn't reported. Additionally this same change was made to the captureLambdaHandler at some point in the past.

This PR modifies the logic of the captureMethod decorator and updates the unit tests related to it so that they actually test a method that throws.
