MINOR: Fix bug in `waitUntilLeaderIsElectedOrChanged` and simplify result
type
The bug was for the following case:
`leader.isDefined && oldLeaderOpt.isEmpty && newLeaderOpt.isDefined &&
newLeaderOpt.get != leader.get`
We would consider it a successful election/change even though we should not.
I also changed the result type as we never return `None` (we throw an
exception instead).
