Investigate status processing

[jSylvestre]

An invoice is stuck in the processing status.
It looks like it happened because the money movement job didn't create the transactions (fees, etc).
This could have been because the invoice was done before we made some changes to including accounts/default accounts.
Or maybe something happened with sloth like the account was no longer valid?

Invoice 654

Setting the invoice back to paid may give this a change to fix itself...
