``channel_id`` field is used to compute ``render_model`` of invite wizard
used to filter templates to choose. It is a fake trigger ensuring the
render model field is computed, and then used in template domain
(see ``mail.composer.mixin`` and ``mail.render.mixin``).
As channel_id field is not available in view the domain computation for
template_id is not updated. No template is therefore available in template
m2o field in invite wizard. This commit fixes that by adding the channel_id
field in the view, meaning render_model is now computed.
