Remove unused dependency from pagesuggester

This is a follow-up to I44a2240 and later patches in the same
chain. I'm aware some of these changes are a matter of taste.
This patch is mainly meant as a collection of suggestions.

I'm pretty sure about the dependency but it would be good if you
could check this.
