Fixed lazy loaders injection

AbstractSearchService::getByFilter() wasn't injecting lazy loaders,
because it didn't call AbstractDao::afterLoad(). This resulted in tags
not showing up in post list, because there was nothing to retrieve them.
Changed lazy loaders injection so that it's always executed as soon as
possible (i.e. right in EntityConverter).
