Revert "Only load Helper::ResultSet::SetOperations instead of all"

This reverts commit 506817e57cf649d5bf077a2f544fef53b52bfffa.

This commit breaks master (no "count" available for example).
Only load certain Helper::ResultSet::*

this fixes the bug in certain versions, when we did
$resultset->getColumn(*)->all
which was introduced  by DBIx::Class::Helper::ResultSet::RemoveColumns

this time we will not break anything again
