Fix regression in d58e426d6233534d12cbd07332162d663303d714

In commit d58e426d6233534d12cbd07332162d663303d714 set -e was added in order for
the script to exit on errors since it would just continue trying to do things
otherwise. This didn't play well with `grep` that returns exit code 1 when it
doesn't match.
