[webconfig] fallback to default configs if https ones are not defined When cubicweb serves a request with an https scheme, it tries to access ``https_uiprops`` and ``https_datadir_urls``. However if those are not defined we should fallback to unsecure url instead of crashing with a traceback. There are very valid usecases for undefined https url. For example if your ``base_url``, ``datadir_url`` and uiprops content are already https urls. Closes #2786643
