svn subrepos: work around checkout obstructions (issue2752)

We do this by ensuring the working copy is clean and then blowing away
the working copy and replacing it with one from the desired path. We
could probably use 'svn switch' to do this more efficiently, but
there's some subtle logic required to get that right and this is
more likely to work reliably.
