Do not scatter so much between Business Templates portal type definitions.

This reverts commit ddeaf310.

Note: Always use pyflakes.

Do it litearally as otherwise it would require or monkeypatching Sequence.

Even more: some test might generate inconsistent objects, so such approach
will give flexibility.

But keep simple assertion.

WARNING: this is an quick ugly hack to not block developper.
The clean fix is to swith to the rest API defined in:
http://packages.python.org/slapos.core/

variation property which comes from Item generates getVariationPropertyList.
VariationRange's property defines variation_property which also generates
getVariationPropertyList

As there is conflict which is not solved by category accessor generation
sorting (which is per property sheet) adding later VariationRange will result
in overwriting accessor for category with own one.

Because of builders begin invoked on each tic packing list is created
immediately.

Follow isBuildable API change -- find and pass Business Link.

Use trade phase to match movements.

Note: Trade phase is setup twice: once on object and then as
membership_criterion_category.
