[PATCH] Redundant creation of svn_client_commit_item3_t's in WC -> repos copy/move operations?

Hyrum, I think we can remove the apparent redundant creation of
svn_client_commit_item3_t's in WC -> repos copy/move operations that
we discussed on IRC.

If for some reason the list of commit items gathered by way of
harvest_commitables() was different than those inferred from the copy
pairs (though I don't think it would be), we'd want to use the
harvested list when prompting the user for a change log message
anyways.

I think the trade-off here is that we'll end up doing more WC I/O
before prompting the user for a change log message, meaning that in
the failure case -- no log message provided -- we've performed some
extra work. This seems like a very reasonable trade-off for
simplifying the code.
