[Password Manager] Update SQL database version in response to rollback

[Password Manager] Update SQL database version in response to rollback

Version was decreased from 8 to 7 after crrev.com/e8c29d4. This shouldn't
affect very many people since the 7 -> 8 change was broken and no profiles
would be updated, but it would affect Canary users that created new profiles.
To be safe, keep the new version around but without any database changes.
