This order will work just as well, so no need to revert this change
later.

Note that, before it fails, retrieveKeyFile has already succeeded once.
It may be that the cause is that the earlier retrieveKeyFile leaves
the annex object file somehow inaccessible.
Or it may be that the cause is in Command.TestRemote's code
that sets up this "resume from 33%" test case:
loc <- fromRawFilePath <$> Annex.calcRepo (gitAnnexLocation k)
tmp <- fromRawFilePath <$> prepTmp k
partial <- liftIO $ bracket (openBinaryFile loc ReadMode) hClose $ \h -> do
sz <- hFileSize h
L.hGet h $ fromInteger $ sz `div` 3
liftIO $ L.writeFile tmp partial
lockContentForRemoval k noop removeAnnex -- appears that this is what fails to delete the file
If the handle that is opened to read the annex object file somehow
causes it to linger in a locked state past when the handle should be closed,
it could cause the later failure to delete the annex object file, since windows
may consider an open file handle to be a lock.
(Some issues with ghc not promptly closing file handles, in a version
in the last year or so, come to mind..)
I've swapped the order of the resume from 33% and resume from 0%
tests. The 0% test does not open a handle that way. So if the
resume from 0% still fails, we'll know for sure the problem is not
caused by the 33% test.
If it is caused by the CoW changes, it seems likely to involve fileCopier's
code that tries to preserve the source file's mode. Before the CoW
changes, I don't think that was done by Remote.Directory's retrieveKeyFile.
