Update GroupFundFY table

Overview

As funds are associated with groups, and fiscal years are created, we need to make corresponding changes to the GroupFundFY table.

• When a FiscalYear is created, create a new GroupFundFY record for each existing Fund/Group pair.  (only if fiscalYear endDate > now)

See the wiki for details

• NOTE: Don't worry about delete for now... we'll probably need to implement a soft delete for group/fund/fy since they are referred to by several other records.

Approach

• Update the GroupFundFY table in a database transaction, or possibly via trigger function.

Acceptance Criteria

• GroupFundFY records are created as described in the wiki
• Unit tests are updated
