Whilst it's not a good idea to have two electrum instances open on the same wallet, we should avoid throwing an exception. Also note how the old code's handling of the exception (caused by both renaming the file almost at the same time, rather than a non-POSIX system not supporting the atomic rename) can lead to the wallet file being lost enirely because os.remove(self.path) succeeds and the rename of the temporary no-longer-existing file then fails.
