fix(tests): update specs after invite/vacancy repository changes

- invite.repository: add null guard on raw.sender/raw.user in sendForUser (same as getMy/getByProject)
- vacancy.repository.spec: update getForProject mock to return ApiPagination<Vacancy> instead of plain array to match the adapter contract change
