Camptix Invoices: Avoid a PHP Notice if not yet setup.

[dd32]

A semi-annoying PHP Notice is being generated when creating an invoice on the WordCamp site, but the Camptix VAT ID field hasn't been set.

GET https://xxxxxxxxx.wordcamp.org/2024/wp-admin/post-new.php?post_type=tix_invoice

E_NOTICE: Undefined index: invoice-vat-number
File: wp-content/plugins/camptix-invoices/camptix-invoices.php:261
Stack Trace: require('wp-admin/edit-form-advanced.php'), do_meta_boxes, ctx_invoice_metabox_editable

This doesn't appear to indicate anything is wrong, just that the specific settings haven't yet been updated.
