test: remove flaky test from volumewatcher (#8189)
test: remove flaky test from volumewatcher (#8189)

The volumewatcher restores itself on notification, but detecting this is racy
because it may reap any claim (or find there are no claims to reap) and
shutdown before we can test whether it's running. This appears to have become
flaky with a new version of golang. The other cases in this test case
sufficiently exercise the start/stop behavior of the volumewatcher, so remove
the flaky section.
