[FIX] mrp_subcontracting: fixes the breadcrumb issue indicates 'projects' twice

Steps to Reproduce:
- install service apps and website
- install website related bridge modules
- install quality and related mrp_subcontracting bridge module
- click on website , click on My account
- click on project ,or timesheet,or tasks,or tickets

Issue:
- after clicking,we will notice that breadcrumb  indicates 'title' twice

Cause:
- this is because,in mrp_subcontracting , the title for productions is given
  without checking the page_name , so that will affect all the titles.

Solution:
- if we gave condition to check the page name for production this issue is
  solved.
