notebook: Fix a misplaced tab label

Browse Source 
Sometimes default tab labels ("Page <n>") get created on-demand,
and in that case, we were forgetting to put them below the tab
node in the CSS node tree. The visible result of this is that the
heuristics for when to give notebooks background in Adwaita fail
in some cases. So, make sure to always place the label below the
tab node.
