When a user updates the preferred name, we should just ignore if the name is an ENS name,
because the ENS name is set only in the ENS popup. But this also means that if a user set
the profile name to an ENS name, this change will also be ignored.
- use `appdatabse.DbInitializer{}` in tests to ensure consistent migrations
- remove protocol's open database functions due to improper
initialization caused by missing node config migration
- introduce `PushNotificationServerConfig` to resolve cyclic dependency
issues
Added a unit test for changing app and wallet DBs passwords.
Refactored geth_backend to simplify and allow wallet db password changing.
Fixed opening database with wrong password.
The only place where appDB is used in wallet is activity,
which refers to `keycards_accounts` table. So a temporary
table `keycards_accounts` is created in wallet db and updated
before each activity query.
