[Pharo-project] FontTest depends on curent styles

Two test in FontTest assumes what TextStyle>>default will answer a some Accuny font with some size. But if we override default font - test will fail. I'll try to find solution and fix, but new vm and image crashed during debuging. I think solution will be to create corresponding TextStyle for test. Also i'm a newbie and can some clarify what is DefaultTextStyle? It not declared as instance or class variable.
