[16.0][FIX] account_invoice_overdue_reminder: wysiwig-friendly html code

[hbrunn]

when editing the template with odoo's built-in wysiwig-editor, it will pull the two loops above the <table /> node, as in

<t t-foreach="object.invoice_ids.sorted(key='invoice_date')" t-as="inv" />
<t t-foreach="object.total_residual()" t-as="total_residual" />
<table>
...

which renders the template basically defunct. Instead of teaching customers not to edit this template specifically (the editor works as expected when the qweb attributes live on structural nodes), I suggest to change the template such that it survives editing.

I very much disagree with what prettier did here, but that's what it did.
