Fix declaration of override method in IdentityManagerObserverBridge

IdentityManager::OnRefreshTokenRemovedForAccount() expects as a first
parameter a "const std::string&" instead of a "const AccountInfo&",
so this patch fixes it to prevent build failures when using this API
because of OnRefreshTokenRemovedForAccount(const AccountInfo&) not
being a valid override for the virtual method declared.
