Remove AllUsersName from AccountState

AccountState grew a field referencing the name of 'All-Users'. This
field was populated solely for indexing. We want to reduce account state
to the bare minimum information in a sense that it only carries fields
that relate to the account and make the entity immutable if possible.

This commit removes the field and migrates callers. It is perfectly fine
to index an account and build the REF_STATE from the default name. This
is only ever used for checking staleness of the account document where
we have the real All-Users name available for usage.
