Add helper methods to tab widget for view containers

This commit introduces the private getter
DolphinTabWidget::viewContainerAt(ViewIndex)
and another private method
DolphinTabWidget::activateViewContainerAt(ViewIndex).

Both methods return nullptr if there is no valid
DolphinViewContainer at the specified ViewIndex.
