Corregido

Fixed the test suite failing on two unregistered scripts

The invoice reminder sender and the Google profile picture copier are declared in the area registry, which every entry point must be.

AreaRegistryTest checks that every script in bin/ and every page in public/ declares its area, and failed on bin/send-invoice-reminders.php (Invoicing) and bin/copy-google-profile-pictures.php (an admin script). Both are registered. Nothing changes for the scripts themselves.
