Comment (by nickm):

 The rule is approximately: we should only extend circuits on is_canonical
 channels.

 Right now, we enforce this by checking is_canonical when we call
 channel_get_for_extend.  But perhaps we should also check it when we *do*
 the circuit extend to make sure that the same check is still true.
