add module logistic_consignee
- extract consignee_id field from logistic_order
transfer consignee from purchase-workflow modules
add pot file
add dependancy on logistic_consignee
change tooltip to match with other
split tests as consignee is a mandatory field
reorganize the tests
add dependency on logistic_consignee in logistic_order
fix test data
correct travis config

We need to run the unit tests for logistic_consignee separately from the rest
because other modules in this repo will install purchase_rfq_bid_workflow and
the unit tests of logistic_consignee create PO which are not in the correct
workflow.
