test: do not check text for engine-generated error

In test-tls-wrap-event-emitter, the text of a TypeError is checked as
part of the test. However, this text is generated by the JavaScript
engine (V8) and not Node.js. Thus, we should not check the text as JS
engine error messages can change without it being considered a breaking
change for Node.js.

A side effect is that node-chakracore will no longer need to patch this
test to pass.
