Packaging doesn't include non-imported python file because
redhat. Oblivious, revision 8e81abfeb5
renamed .py.template files to .py thus breaking scaffolding from
packaged odoo.
Revert that specific change.
Fix#11050
NB : Some tests have been modified.
One assert statement in orderpoint_calendar.yml has been modified,
but the change is legit has no python method has been modified at all
Add .template as extension of the template files because RPM packaging
produces an error when trying to compile the python template files,
which contains Jinja instructions.
Include *.template files in MANIFEST.in to package them.
