[libvirt] [PATCH libvirt-glib v2 2/8] Ensure internal copy of URI is not NULL

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

It is permissible to pass in NULL for a URI to libvirt, which
causes it to probe for a supported driver. In such a case we
should populate priv->uri with the resulting probed URI after
opening the connection

* libvirt-gobject/libvirt-gobject-connection.c: Populate URI
  after opening connection, if NULL
