fix(db-mongodb): fallback version when not selected (#12158)

When doing `payload.db.queryDrafts` with `select` without `version`, or
simply your select looks like:
`select: { version: { nonExistingField: true } }` - the `queryDrafts`
function will crash because it tries to access the `version` field.
This PR adds a fallback.
