Proposed patch

Description of problem:
virt-manager 1.2.0 fails to list VMs when host's libvirt does not support the virConnectListAllDomains() call.

Version-Release number of selected component (if applicable):
1.2.0

How reproducible:
Always

Steps to Reproduce:
1. Use virt-manager 1.2.0 to connect to a host using libvirt version <0.9.13 (e.g. RHEL 5.x).

Actual results:
An error message stating "Error polling connection '<libvirt-URI>': 0" is displayed.

Expected results:
VMs on the selected host should be listed.

Additional info:
I believe this is caused by the changes to virtinst/pollhelpers.py introduced in commit 838baf6 - _new_poll_helper() and _old_poll_helper() are modified, but not _old_fetch_vms(), which is used for hosts with old libvirt versions. Applying the attached patch fixed the problem for me.
