[WIP][16.0][FIX] account_move_name_sequence: build invoice name from journal entry sequence

[ljsalvatierra-factorlibre]

Steps to reproduce the error:

1. Create a Journal with an entry sequence with prefix not equal to the journal short code (e.g.: B2CSEQ vs B2C)
2. Create an invoice, set the default sales journal and save the form
3. Edit the invoice, set the journal created at 1) and save the form, you should see the invoice name with the short code instead of the prefix from the entry sequence. It is possible that you have to change the journal multiple times to trigger the bug.
4. Post/Confirm the invoice, should have the wrong prefix
