If no module is selected, check nothing.

There is no control where context would be used.

remove Delivery_viewSolveDivergenceDialog in erp5_base because it already exists in erp5_simulation or erp5_simulation_legacy.

add a hidden field in Delivery_viewSolveDivergenceDialog so that user are forced to update the dialog first.

fix a condition of Person_view/my_default_email_url_string so that only one email field is displayed on a new Person document.

changeTranslations was removed in c60e89fe in favour of single-value,
better-named setter.

Otherwise, deleting objects and packing would not free memory.

move delivery builders from erp5_simplified_invoicing to erp5_simulation_test and make invoice builder global.
