Fix flaky DataImportCron volume snapshot test

As commented by Alex Kalenyuk: the condition check flakes because the
switch to snapshot boot sources is almost instant. The DataImportCron
never becomes "not ready" following the switch. We also moved the DIC
"ready" check after the snapshot "ready" check, otherwise we may check
it before it's "not ready", which checks nothing.
