Don't check the 'connect' command in virsh-all test

The 'virsh-all' test case will invoke each virsh command with
no args. With the 'connect' command this causes virsh to try
to connect to the default URI, which in turn tries to spawn
libvirtd. This is not something we want todo in the test suite,
so skip the 'connect' command.
