QWeb's rendering currently *requires* that when loading a document
instead of rendering the document itself it will render a sub-node
with a properly labeled t-name. If a view is invoked by id, ir.qweb
will look for a child with a t-name and fix up that t-name such that
the base qweb object will find and render it.
This feature mostly exists for JS compatibility (because a single
document can contain multiple cross-linkable templates, and it was
useful for cross-implementation tests though I'm not sue they're even
checked anymore), and the <template> tag kinda took care of it,
however with a more proper qweb view it becomes more of a liability /
pain in the ass.
Note: turns out there are bits of javascript which read server
templates (???) and need to be altered to correctly handle the lack of
<templates> wrapping.
