configurator_standard: use specific sale and purchase business processes

Using different business process is more flexible, it allows to configure
different to build at different time, to generate different accounting etc.

This introduce two different business processes and also modernize the configuration to:
 - generate accounting only for the supplier in sales
 - generate accounting only for the client in purchases
 - generate accounting using income/expense accounts defined on supplies
 - generate accounting without analytics (project, function) only for
   income/expense accounts

and to fix an "infinite loop" with tax business link, it had the same
predecessor and successor
