fix: reload old wallets (#6308)

Description
---
This allows older wallets that dont have a type stored in the DB to load
up as software wallets.

Motivation and Context
---
If this type is not stored, either the entire DB is corrupted or its an
older wallet without a type stored.
If the DB is corrupted it would very likely fail earlier, or if not
later. But older correct wallets should not be blocked from booting up

How Has This Been Tested?
