Bug 22393: Remove last remaining use of C4::Accounts::manualinvoice

Bug 22393: Remove last remaining use of C4::Accounts::manualinvoice

This patch re-arranges the manualinvoice controller script to clarify
code flow, replaces the last call to C4::Accounts::manualinvoice with a
call to Koha::Accounts->add_debit wrapped in a try catch block and also
adds a check on passed barcodes when the invoice type is 'LOST' so it
can link the subsequently created accountline to the item and issue.

Test plan
1/ Add a manual invoice (without entering a barcode)
2/ Add a manual invoice with a valid barcode (Not a LOST type)
3/ Add a manual invoice with a valid, but old, barcode (Not a LOST type)
4/ Add a manual invoice with an invalid barcode, note that an error is
displayed
5/ Add a manual invoice with type 'LOST' and a valid barcode for a
checkout your user has had checked out
6/ Add a manual invoice with type 'LOST' and a valid barcode, but not
one that will match a checkout for your user. Note an error is displayed
7/ When errors are displayed, note the form contains data from the
previous submission so you can just correct the error rather than
re-enter all data.
