Calculate whether we need an expansion row for the banner correctly

Browse Source 
The old calculation did not take into account the icon and the spacing
between columns. This resulted in the notifications that had a slightly
longer title/banner combination than could actually fit not being expandable.

The new calculation is done in _bannerBoxAllocate() so
that we don't need to hardcode which other elements are present.
