[FIX] base: traceback after enabling profiling

before this commit, if profiling is enabled in the db,
and on trying to validate a sale order, a traceback is
shown

* enable profiling
* confirm a quotation

traceback:
Failed to render QWeb template : <div style="margin: 0px;
padding: 0px;">
    <p style="margin: 0px; padding: 0px; font-size: 13px;">

introduced in: https://github.com/odoo/odoo/commit/016f26a9315c693bdeb894725898c2cf725d8989

here the options['ref'] is coming as the email template
body and it is failing on try to do int of options['ref']

after this commit, no traceback wont be shown on
confirming sale order, when profiling is enabled

closes odoo/odoo#138357
