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

[bsra-odoo]

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

Traceback (most recent call last):

    fields[base]['relation'], base, fields[base]['string'],
KeyError: 'move_lines'

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 here (because such field doesn't exists), which leads to failing this condition because of the difference in length of old and new path

Some output from shell for better understanding here :

Genereted new_path

In [20]:             new_path = [
    ...:                 new_field_name
    ...:                 if field.field_name == old_field_name and field.field_model in only_models
    ...:                 else field.field_name
    ...:                 for field in resolve_model_fields_path(cr, 'stock.picking', ['move_lines','.id'])
    ...:             ]

In [21]: new_path
Out[21]: ['move_ids']

Expected new_path

In [22]:             new_path = [
    ...:                 new_field_name
    ...:                 if field.field_name == old_field_name and field.field_model in only_models
    ...:                 else field.field_name
    ...:                 for field in resolve_model_fields_path(cr, 'stock.picking', ['move_lines','id'])
    ...:             ]

In [23]: new_path
