Added code to only return newly created Account objects once they have been saved to the database (or are requested by UUID). This will allow the account creation process to be aborted without the application crashing (see issue 1375).

I don't particularly like this fix and hope to find a more elegant solution to this problem.

Kind of fixes issue 1375
