Accounts have been fully migrated to NoteDb. However inside of Google we
still have code that depends on having all accounts in the Accounts
table. This means we must still write account updates to the Accounts
table. On the other hand also for us Gerrit server is always reading the
accounts from NoteDb. This means the code for reading accounts from
ReviewDb can be removed already now. This is why removing the support
for accounts in ReviewDb is done in 2 parts:
1. remove support for reading accounts from ReviewDb (this change)
2. remove support for writing accounts to ReviewDb (follow-up change)
