[devtools] Use super() in TestServerConfiguration.__init__() While cleaning up the use of init_config() in WSGIAppTC, I wondered why the method was trying to set the 'https_uiprops' and 'https_datadir_url' attributes on the config, when WebConfiguration's __init__ should be taking care of setting them. WSGIAppTC uses the default configuration - one that derives from ApptestConfiguration (noted as G below). The issue is that the class hierarchy of ApptestConfiguration includes TestServerConfiguration (C in the graph below) which calls ServerConfiguration's __init__ directly (B below). As B does not have an __init__ method, CubicWebConfiguration's __init__ is called directly (A below). This has the unintended consequence of preventing WebConfiguration's __init__ from being called. A / \ B D | | C E \ / F | G | ... A: cwconfig.CubicWebConfiguration B: server.serverconfig.ServerConfiguration C: devtools.TestServerConfiguration D: web.webconfig.WebConfiguration E: etwist.twconfig.WebConfigurationBase F: devtools.BaseApptestConfiguration G: devtools.ApptestConfiguration NB: unittest_wsgi wasn't really broken, as it's the only test in wsgi/test/, but I figured I might as well clean it up. Related to #9297611.
