git-rebase--interactive.sh: Quote arguments to test

If /bin/sh is /bin/dash, then the script will display an error if
$parent_sha1 is undefined.  This patch works fixes the issue by
quoting both arguments to `test'.  Arguments composed solely of
variable expansions should always be quoted, unless we know for
certain that the contents are defined.
