CodeOwnerResolver: Return Optional from resolve method rather than Stream

The resolve method either returns a stream with exactly one code owner
or an empty stream. It's easier and more readable to just return an
Optional. Returning a stream is a left-over from when the resolve method
was resolving "*" to all users.
