This version of c9 is a slight fix to 4.874 upgrade

The DB upgrade steps in 4.874 could potentially fail under some exotic circumstances. This update makes the upgrade more resilient.

If you are running 4.874 already then this ver does nothing useful. If you are running a version before 4.874 then this new update includes more robust DB upgrade instructions. This version of itself is not a db upgrade version.

Technical specifics: bankrecitem update enforces non-null on reconciled amount but it is in theory possible to have a bankrecitem without a corresponding journal posting. To fix, this ver will write these in with a zero value to avoid null constraint check.
