Since 15.2, when creating an invoice containing both a recipient address and an invoice address, the addresses would both appear on the left, one after the other.
This made reading difficult and the invoice unclear.
Furthermore, the company address wasn't present by default on the invoice : it was only there if a layout had previously been selected.
This PR:
- reverts the behaviour of the company address, i.e. it appears even if no layout is (yet) selected ;
- aligns the delivery and the recipient address on each side of the page when necessary, while not changing the outcome if a single address is given.
Also displays a "title" above the addresses when necessary to make things clearer.
