The conflict has been resolved by accepting the solution by the cherry-picked commit,
and then afterwards moving the changed code from the above commit to the relevant position.

After ERP5's 992c0ff13e8b5ac78cca4e7195de383418291892 we need to explicitly add this bt5 dependancy.

This patch is similar to
nexedi/erp5@530e8b4e
(nexedi/erp5!1445) and amends Wendelin test
driver to run tests on a real storage and spawn WCFS as needed.

Running tests on a real storage instead of in-RAM MappingStorage is
required in wendelin.core 2 case, because WCFS and Zope need to access the
same ZODB, and if Zope keeps data inside in-RAM MappingStorage, there
is no easy way for WCFS to access it. In such a case tests are failing as e.g.

-> Fix it by using a real storage for tests via --load/--save hack, and via
--with_wendelin_core requesting to spawn WCFS when built with wendelin.core 2.
