[FIX] web, web_kanban: make qweb default dict configurable

In a previous refactor, qweb configuration was simplified.  However, I
missed the fact that session.js sneakily configure the qweb instance
after the fact. As a result, the kanban view did not have the _s key in
its custom qweb instance default dict.  This commit allow the qweb class
constructor to add default keys to the instance.

Now, kanban view can add _s, and everything is good.
