Fix some issues with the can-component paginate demo
Fix some issues with the can-component paginate demo

- Use base-map instead of super-map so the can-fixture delay is actually perceivable
- Remove an unnecessary `leakScope: true`
- can-define ignores return values from setters that also take a resolve function, so call resolve() multiple times within a setter
- Use #if() to avoid can-stache’s “unable to find key” warning
