[FIX] util/fields: ensure path update for ir_exports_line

Issue: When exporting data using the existing export
template, a traceback error occurs.

Cause: When a field is renamed, the path in `ir_exports_line`
is not updated if it contains `.ids`. This happens because
the resolve_model_fields_path fails to retrieve the field

record from `ir_model_fields` where the field name is `.id`,
which leads to failing this condition because of the difference
in length of old and new path

closes #133
