[epiphany] uri-tester: Receive the base data dir as construct property instead of using ephy_dot_dir()

[Carlos Garcia Campos <carlosgc src gnome org>]

commit c450d2e819340175b6db5804208154f0382fc0fc

    uri-tester: Receive the base data dir as construct property instead of using ephy_dot_dir()
    
    This removes the dependency of ephy-file-helpers from uri-tester, that
    will make easier to use it from a WebKit2 web extension
