SQL: Save commodity namespace changes from template

When loading commodities erroneously made in namespace template,
gnc_commodity_table_insert changes the namespace to User. This
change wasn't being committed, requiring that it be changed every
time.

The obvious immediate commit didn't work because the SQL backend
suppresses commits during load for performance, so create a list
of changed commodities to commit later, then do so.

Thanks to Geert for noticing the problem and to Derek for suggesting
the list workaround.
