Console import progress off-by-one

[robproject]

Description of the issue

Data import utility displays incorrect progress in console mode due to off-by-one error since frappe.publish_realtime() takes 1-indexed progress while update_progress_bar() takes 0-indexed.

Steps to reproduce the issue

Import any import file as is intended to be used.

frappe.core.doctype.data_import.data_import import import_file

import_file(doctype, file_path, 'insert' or 'update', console=True)

Observed result

Importing 4 records                 : [==================================================] 125%
Successfully imported 4 records out of 4

Expected result

Importing 4 records                 : [==================================================] 100%
Successfully imported 4 records out of 4
