function ExpectDeprecationTrait::setUpErrorHandler

Sets up the test error handler.

This method is run before each test's ::setUp() method, and when the DeprecationHandler is active, resets the extension to be able to collect the test's deprecations, and sets TestErrorHandler as the current error handler.
