Reduce page_props usage

Don't save page_top_level_section_count=0,
treat the lack of property as zero instead.
That would reduce page_props usage by 23% on enwiki, or 6.5M rows.

Note: Although lack of property could also mean the talk page count
hasn't been computed this code has been on enwiki for some time
let's not worry too much about this edgecase.
