[FIX] purchase_product_matrix: Allow to change PO lines order

What are the steps to reproduce your issue ?

    1. Install 'purchase_product_matrix'
    2. try to edit a PO with more than one line
    3. try to change the order of a product line

What is currently happening ?

    Traceback: TypeError: Cannot read property 'data' of undefined

What are you expecting to happen ?

    Change order lines without traceback

Why is this happening ?

    There is a function 'reset' that checkes if 'ev' exists:
    https://github.com/odoo/odoo/blob/e0af10ccc92cb3b07f0eea6fa44ebf5a1bdc86aa/addons/sale/static/src/js/product_configurator_widget.js#L119

    And in 'purchase_product_matrix' there is a override of this same function that calls it
    and then tries to use an 'ev' attribute without checking it before

How to fix the bug ?

    Check 'ev' before accessing it
