HydroModeler: DbWriter Does NOT work with older components

Castronova[CodePlex]
When developing the Load Calculation model, the DbWriter was modified to handle multiple data series. It relies on getting series data from the database (see line 456) and fails when data does not already exist in the database. This component needs to
be modified to work with both the older and newer components.

Locate the DbWriter implementation and inspect the database-series handling around line 456, as described in the issue. Reproduce the failure with data absent from the database, then verify that DbWriter works with both older and newer components without requiring pre-existing series data.
