make sure to set result count when initializing pager

This caused request like /outings/list/onam/Lynx/act/4 to fail because
count was set to 4 (because of?) and not reseted, and lead to
invalid SQL

Furthermore I don't think that there are cases where a pager calls
init() when it is not useful
layout light doesn't exist anymore
