PR removed outputs from account-map that iam-roles relied on. Although it removed the references in
iam-roles, this imposed an ordering on the upgrade: the iam-roles code had to be deployed before the module could
be applied. That proved to be inconvenient. Furthermore, if a future account-map upgrade added outputs that
iam-rolesrequired, neither order of operations would go smoothly. With this update, the standard practice of applyingaccount-map`
before deploying code will work again.
