[extensions-web] Use mixins for testing, not copy-paste code

[Jasper St. Pierre <jstpierre src gnome org>]

commit adf183fdacaeb4fd3974ca9785c90d779314f085

    Use mixins for testing, not copy-paste code
    
    Unfortunately ut2.TestCase doesn't use super() in its dummy setUp() and
    tearDown() methods, so we can't "properly" use a mix-in by appending
    it to the end of the list.
