[FIX] base_import: parse date and float for relational fields

Use case to reproduce:
-> Import a file with a float using a coma related to the model
(for example the product.supplierinfo/price)

It happens because the method that parse the date and float field
only compare them to the main imported model.

This commit complete the method by using a recursion on relational
model in order to also parse the relational subfields.
