run-test: restore the -i prompt by write .err before checking if it exists
The `--interactive` flag workis by overwriting the original test file by its
`.err` version. So we need to write it before calling `self.fail`. Otherwise the
`.err` file does not exists and `--interactive` is ignored.
We can move that block code around because it is dedicated to write changed
output and we moves it in the try-except dedicated to handling changed output.
Note that the flog is still badly broken after this change. But at least it crash
instead of being ignored.
