Fix error when deactivating an account (#7899)

The RA's DeactivateAccount method expects the account provided to it by
the WFE to still have status Valid. The new WFE deactivation code was
hardcoding the status to Deactivated. Fix the WFE to pass the account's
current status instead.

Add an integration test to confirm both the breakage and the fix. Also
leave behind some TODOs to simplify this codepath further, and not
require the status to be provided at all.
