run-tests.py: fix diff output when test-foo.out doesn't exist.

Previously, if test-foo.out doesn't exist and test-foo outputs
something, the first line of the diff will look like this:

-+changeset:   0:0acdaf898367

(note the leading "-")

#!/bin/sh

hg init a
echo a > a/a
hg --cwd a ci -Ama

hg clone a c

hg clone a b
echo b >> b/a
hg --cwd b ci -mb

echo % push should push to default when default-push not set
hg --cwd b push | sed 's/pushing to.*/pushing/'

echo % push should push to default-push when set
echo 'default-push = ../c' >> b/.hg/hgrc
hg --cwd b push | sed 's/pushing to.*/pushing/'
