Subject: [PATCH] fix: customer_group import from lead to customer (#48266)

In case customization happens and the lead has the field "customer_group", the get_mapped_doc function would fail and be overwritten by the default value.

(cherry picked from commit 1b18105bce90b770264e741f8951708eb53b35e1)
