[IMP] web: prevent jquery from throwing error at start

To test which browser is currently running, jquery performs some checks
when it starts, by doing invalid queryselectors. Depending on which
selectors crashes, it can determinate if it is running in an old browser
and need to activate some part of the code to support them.

This would not be a big deal, except that it makes the life of some
developers much more difficult: we can no longer easily reload a page
with a "Pause on exception" setting to debug odoo. Doing so works, but
the workflow is polluted by 3 errors initially.

It is so common that I propose to simply remove the checks. This should
be acceptable, since Odoo does not work on old browser versions anyway

We are talking about firefox 5, opera 11 or "Gecko", for a commit that
is at least 11 years old

closes odoo/odoo#136013
