src: fix error message in async_hooks constructor

There are two minor issues in the AsyncHook constructor, if the object
passed in has an after and/or destroy property that are not functions
the errors thrown will still be:
TypeError [ERR_ASYNC_CALLBACK]: before must be a function

This commit updates the code and adds a unit test.
