Overview

Avoid dynamic properties in CRM_Contact_BAO_ContactType_RelationshipTest

Before

Use of dynamic properties, deprecated in PHP 8.2. See https://lab.civicrm.org/dev/core/-/issues/3833 for context.

After

The properties are not declared dynamically, the tests should pass on PHP8.2.

Some of the properties were not used, so have simply been removed.
