[FIX] odoo_sale_order_line_views: Warning raised by typo in manifest key: "license"

The word 'license' can be written "licence" too but odoo expects
"license".

The fallowing warning was being raised, even when the module was not
installed.

WARNING ? odoo.modules.module: Missing `license` key in manifest for
'odoo_sale_order_line_views', defaulting to LGPL
