Bugzilla

There's some discussion over in Bug 1044456 that implies this test is irrelevant under maildir... but I'm not sure. Still looking into it. If that _is_ the case, it needs to handle maildir anyway (even if that's just to skip or bail out early).

Works fine when mbox is the default store type, but under maildir it just hangs while waiting for a 'msgsClassified' notification.

To replicate, switch to maildir as default, in mailnews/mailnews.js:
```
-pref("mail.serverDefaultStoreContractID", "@mozilla.org/msgstore/berkeleystore;1");
+pref("mail.serverDefaultStoreContractID", "@mozilla.org/msgstore/maildirstore;1");
```
and run the test:
```
$ ./mach xpcshell-test comm/mailnews/search/test/unit/test_quarantineFilterMove.js
```
