erp5_project does not depend on erp5_budget, so instanciating project
cell fail unless erp5_budget is installed.

Project Cell are not used by default, so it's still a bit unclear, but
with erp5_budget we can directly define budgets by project / project
lines in a more flexible (but also more complex).

Project Line uses OrderLine, so it's consistent to use OrderCell for Project Cell.

erp5_trade_ja: 軽減税率8% tax line in summary must always be present (official specification) but is not used in Nexedi so hardcode it.

erp5_trade_ja: AttributeError was raised when default_image (to display logo at the top left) was not defined.

- views/actions meant for officejs should use "object_jio_x" categories to avoid conflicts with erp5js
- using object_jio_search instead of common object_jio_view because the base form for rendering depends on the category (form_list, form_dialog, form_view, etc)
- changes are also in bts officejs_jquery_app and officejs_ooffice

- do the calculations while officejs router set settings

 - run `testXHTML` on business templates "one by one"
 - fix all the problems with the currently tested business templates
 - because `erp5_ingestion` was containing some tests skin folder depending on other business templates and because I did not want to add dependencies to `erp5_ingestion` I moved the tests in `erp5_ingestion_test`.

This will allow to find problems when only business templates and their
dependencies are installed. When we run testXHTML with all business
template installed we don't see problems that may happen only when some
business templates are not installed.

There are no testVifib (at least not in nexedi/erp5 repository) and
there is only one testLive that there is no reason to skip.

This test never ran because we skip testLive*

erp5_ingestion contained a skin folder for tests, with some proxy fields depending on erp5_web.
There was a proper test dependency to erp5_web, but in static analysis check we now check the skin folders, so it's no longer allowed to have some skin folder that are broken without test dependencies but not supposed to be used outside of tests.
