Dequeue invoice from consolidation

When an account has consolidate billing enabled, invoices that are generated in the middle of the billing cycle from upsells or new subscriptions, for example, will enter into a pending state. When the next bill run executes for the account, all pending invoices will be combined into a new invoice and the pending invoices will transition to consolidated state.

Dequeuing an invoice will return it to draft state if draft invoices is enabled, other it go to due and possibly be emailed to the customer.
