PanelBar fires onSelect twice if you click on a label element inside its template

[marin-bratanov]

Bug report

When you place a <label> inside the template of a panelbar, and click on that label, the select event fires twice instead of the expected once.

Note: works as expected on collapsible items, only items without children exhibit the problem.

@Juveniel After the fix expanding clicking on a PanelBar item with contentUrl navigates to that URL. Also it is not possible anymore to expand such an item with keyboard Enter/Space key.
To reproduce the issue, use panelbar/ajax demo (all items) or panelbar/events demo (Ajax Item and Error Item)

@Juveniel After the second fix, it is not possible to expand PanelBar item with contentUrl at all (clicking on it or through keyboard). Use kendo-ui/panelbar/ajax demo for reproduction.

@Juveniel Clicking on the expand arrow icon of a PanelBar item with contentUrl navigates to that URL.
