Add missing file argument to iniset_multiline

Change Id9aab356b36b2150312324a0349d120bbbbd4e63 introduced a call to
iniset_multiline to enable swift stores explicitly. However, the call
has a missing file argument which resulted in this call setting the
values to the wrong file, section and param. This patch fixes that.
