evolve: don't use exception for local flow control
The LocalMergeFailure class was added in 3f91654713dd (obsolete Move
merge failure handling into stabilize code, 2012-08-20). I think the
"if compat.hasconflict(r)" check was added later. Now that we have
that check, we should use that for flow control instead.
Note that this means that any unexpected exception from
_relocatecommit() will now just raise (and roll back the
transaction). I think that's an improvement.
