6361074174Finishes the transition to make remote methods throw exceptions, rather than silently hide them. A bit on the fence about this one, because when renameExport fails, it falls back to deleting instead, and so does the user care why it failed? However, it did let me clean up several places in the code. This commit was sponsored by Ethan Aubin.
