Add four test cases for "virsh uri" command

This patch adds four test cases for "virsh uri" command.

Use four cases:(1) Call virsh uri
               (2) Call virsh -c remote_uri uri
               (3) Call virsh uri with an unexpected option
               (4) Call virsh uri with libvirtd service stop
