Bug 798320 - Error message indicating a crash of GNUcash when closing...

application - MacOS 10.15.7 (19H1419)

Destruction order problem: The SX template accounts can't be destroyed
until after the template splts and transactions are.

Register them before the transactions and splits, as destruction occurs
in reverse order of registration.
