[FIX] account_chart_update: Don't cache recordsets
[FIX] account_chart_update: Don't cache recordsets

When marking methods as ormcache, you can't return recordsets, as they keep
the cursor information, and that cursor can be closed (worker spawn for example)
when you need to access again data.

This is fixed returning IDs instead, and browsing when needed
