[IMP] *: do not specify unwanted defaults in default_get

When default_get is called, the wanted fields are specified through the
fields_list arg.  It is useless to fill the values for unwanted fields.

As default_get is called for nearly all records creation, simplifying
the default_get overrides:
* remove potential wrong side-effects of the values
* remove some useless or wrong  defaults computations (searches, refs,
...)
