Every change to a filter (a rule or reference removed or added, the XML
edited) undefined it and defined the new XML. libvirt refuses to
undefine a filter a running VM uses, so none of these worked on such a
filter; on an unused one a refused definition was undone by defining
the old XML without its UUID, so the filter came back as another one.
The filter is now defined again with its own UUID, which libvirt does
in place, while VMs use it too; XML it cannot parse or apply to the
running VMs is refused and reported. The XML editor shows the UUID.

131 test modules sat next to the code they test; instances alone had
51 of them beside views.py and utils.py. They move into a
tests/ package per app, and the JavaScript checks into
webvirtcloud/tests/js. Each non-empty tests.py becomes tests/test_views.py;
the empty generated stubs are removed.
Imports of the app's own modules become absolute, paths built from
__file__ go one level up, the live helper is instances.tests.livetest,
and coverage omits */tests/*. The suite discovers the same 960 tests as
before.
