accrual: Make accruals consistent by entity on the accrual side.

It is more common than I realized that we split an invoice by
entity on the accrual side, so this supports that better.

It still disregards inconsistency between accrual entity and payment entity
for reporting purposes, to help keep reporting clean around automatic
imports.

The changes to BaseReport._report shook out because at this point, the group
key is effectively arbitrary and shouldn't be used for any reporting
purposes.
