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.

+Threading the message also involves displaying the from and to contents,
+which requires opening the message file. The alternative to the fix I
+provided is to just parse all of the message headers when first opening
+the message; it could then be immediately closed and the hash referred
+to for all header data. Given the choice, just having the caller say
+when it has finished with a message is probably a reasonable option...
