Auditing; fails where auto-sequenced code generated

Auditing fails to correctly save details where an auto-sequenced code is generated for an existing record.

E.g. Open and edit an existing Account, blank the code and save. The code is updated to the next auto-sequence - but there is no audit record.

This is now correctly audited. The audit record also notes "Code was auto-generated".

Note, this applies to Account and Client records.
