[FIX] qweb: t-call can be called with an id

Following the new studio features, the use of t-call in templates with
the id occurs. Doing the verification of the integer type of the template
in addition to checking whether the value of type string is a number or
not should be done at different levels. It is therefore simpler to ensure
that the value is a number or an xml_id in compile which is the entry
point of the render and t-call.

The cache made on compile does not change because we have no case where a
template is called with a number of type string in addition to being
called with an integer.
