Filter out Organizational accounts not in the ACTIVE state (#981)

When selecting Organization accounts to be included in the SEA Uninstall
process, those in the SUSPENDED or PENDING_CLOSURE state are included.
This leads to a failure whereby the SEA IAM role cannot be assumed for
these accounts. This change filters all accounts not in the ACTIVE
state.
