Not writing redirection rule for SEM pages(Not a primary location) in .htaccess

There is no redirection rule added for the SEM pages in .htaccess after cancelling the AdvertID having SAID(which is not primary locationID)

Steps to reproduce

1. Deploy a SiteGen request having two line items
BFID:1000000428
SAID:175
Satus:PAUSED

BFID:1000000428
SAID:733
Satus:PAUSED

2. Site will get generated for the request which has 175 i.e, Campbeltown as a Primary LocationID.

Check the site in Jboss (inside jail /var/www/sites/www.<bpid>.com)

As 175 is the primarylocationID SEO and SEM pages were created for SAID 175 (locksmithscampbeltown.html & sem-locksmithscampbeltown.html)

SEM page is created for SAID 733 (sem-locksmithsreading.html)

3. Redeploy the SiteGen request by sending CANCELLED status for line item 2
BFID:1000000428
SAID:175
Satus:PAUSED

BFID:1000000428
SAID:733
Satus:CANCELLED

Actual behavior: SEM page of SAID 733(sem-locksmithsreading.html) get deleted and no redirection rule is added in .htaccess

Expected behavior:SEM page of SAID 733(sem-locksmithsreading.html) should be deleted and redirection rule should be added in .htaccess

NOTE: This is an existing behavior currently in production
