    libvirt-machine-props: Refresh volume info after resize
    
    For running machines, we make use of special libvirt API that operates
    on GVir.DomainDisk rather than GVir.StorageVol and its the latter Boxes
    reads current capacity info from (actually there is no way to read
    capacity from GVir.DomainDisk) so what happens is that when you change the
    capacity of a running machine, get out of properties and back again,
    you find the capacity to remain unchanged even though the actual
    capacity was changed.
    
    This patch fixes the issue by refreshing the storage pool and refetching
    the volume info after changing the capacity through GVir.DomainDisk.resize.
