[FIX] sale_product_configurator, web: fix warning

This commit fixes an issue with the product configurator where if a
subproduct contains an on sale warning, the subproduct won't be added to
the quotation when the main product is added. In order to fix this issue,
it was needed to provide a way for the allowWarning option to be passed
from the addNew method of the basic_relational_model to the
_applyX2ManyChange method of the basic_model. This is done by propagating
the option through the command until it reaches the basic_model.

Since the issue is no longer present in 16.3, this forward port only
adds the test.
