test: rearrange the test corpus into subfolders, fix tests

We will need this for improved folder search tests, but having some
folders should exercise our code paths better anyway.

Modify the relevant test accordingly to make it pass.

This reorganization triggers a bug in the test suite, namely that it
expects the output of --output=files to be in a certain order. So we
add the fix for that into the same commit.

This mainly involves sorting, although the case --duplicate=$n
requires more subtlety.

+
+Hello to all,
+
+I have just heard about Not Much today in some random Linux-related news
+site (LWN?), my name is Adrian Perez and I work as systems administrator
+(although I can do some code as well :P). I have always thought that the
+ideas behind Sup were great, but after some time using it, I got tired of
+the oddities that it has. I also do not like doing things like having to
+install Ruby just for reading and sorting mails. Some time ago I thought
+about doing something like Not Much and in fact I played a bit with the
+Python+Xapian and the Python+Whoosh combinations, because I find relaxing
+to code things in Python when I am not working and also it is installed
+by default on most distribution. I got to have some mailboxes indexed and
+basic searching working a couple of months ago. Lately I have been very
+busy and had no time for coding, and them... boom! Not Much appears -- and
+it is almost exactly what I was trying to do, but faster. I have been
+playing a bit with Not Much today, and I think it has potential.
+
+Also, I would like to share one idea I had in mind, that you might find
+interesting: One thing I have found very annoying is having to re-tag my
+mail when the indexes get b0rked (it happened a couple of times to me while
+using Sup), so I was planning to mails as read/unread and adding the tags
+not just to the index, but to the mail text itself, e.g. by adding a
+"X-Tags" header field or by reusing the "Keywords" one. This way, the index
+could be totally recreated by re-reading the mail directories, and this
+would also allow to a tools like OfflineIMAP [1] to get the mails into a
+local maildir, tagging and indexing the mails with the e-mail reader and
+then syncing back the messages with the "X-Tags" header to the IMAP server.
+This would allow to use the mail reader from a different computer and still
+have everything tagged finely.
+
+Best regards,
+
