feat: added totals tests for end 2 end RMA flow (#8906)

what:

I've added some specs and comments in the specs for where I think totals are incorrect. 

Lets get this test merged in as the status quo and proceed to fix these issues one by one.

Additionally, this also removes the temporary_difference as its not something we use. 

RESOLVES CC-346
