During the merge of qweb/ir.qweb at commit 9ce5bc8881,
the behavior of qweb was preserved instead of the one from ir.qweb.
Rendering inline templates should not be allowed as it is not needed and
include security risks.
Also, minimizing the number of possible types for template arguments
simplifies the API. An error message allows the developer to know how to
adapt his code.
