Before, when sending an invoice for the first time, it would give
a "cannot find savepoint" traceback upon wanting to release it.
We avoid that error by putting less code in the with statement,
so the savepoint gets released a lot earlier while the record
remains locked for the rest of the transaction.
We also put a nice error message if the user can not send at the
moment because another process is already sending. (might happen
more often in v15)
We also updated the translation .pot as we added a new message
and some messages were missing anyways in the .pot, so we added
those as well.
