fix: prevent duplicate options and broken focus on answer creation

Remove the premature `update:answer` emit from `createLocalAnswer` in
AnswerInput — after commit 61b3f48 passed the index correctly, both
`updateAnswer` and `onCreateAnswer` were adding the new option, causing
a duplicate (one without server ID, one with) that appeared unsaved.

Also fix a misplaced closing parenthesis in
`QuestionMultipleMixin.deleteOption` where `optionType` was passed as
the second argument to `$nextTick` instead of to `focusIndex`, causing
`focusIndex` to receive `undefined` as the option type and fail to focus
the previous option after deletion.
