fix shouldCycle conversion when parsing booth information
fix shouldCycle conversion when parsing booth information

`shouldCycle` will be `false` if DJ Cycle is disabled, so
`shouldCycle || true` will then always result in `true` regardless
of the actual DJ Cycle state. This fix only defaults to `true` if
no `shouldCycle` member is present at all (which should be never,
but *shrug* )
