[Popup] .popup('is visible') initially returns DOM element

When the popup never has been opened, the target element is returned instead of false.

Seems there is the same issue with sidebar. When calling "is visible" and it has not been toggled then it too returns the target element.

Thanks for your patience here. is visible was returning undefined in the case where $popup was undefined. This was making the invocation fail and revert to chaining instead of returning the result.

I've modified the booelan to correctly return false.

I don't believe sidebar suffers from the same issue.
