Make LIBVIRT_DEFAULT_URI a fackball mechanism (#1223)

Browse Source 
Switch to only picking up LIBVIRT_DEFAULT_URI if no settings that could
affect the uri have been explicitly set. Some of these may not actually
appear in the URI depending on what is actually set or not set, however
it is important that should only use the env variable if the user has
not explicitly configured options relevant and instead allow them to
configure as needed.
