Deleting a Target List doesn't update the date_modified of its relationship records

[SinergiaCRM]

Issue

If we have a Target List with several related records (Contacts, Leads, Accounts), these relationships are defined in the DB table "prospect_lists_prospects". If we delete that Target Lists, those relationship records are set with "deleted =1" but the date_modified isn't updated.

Expected Behavior

The date_modified of a related relatioship record of a Target List isn't updated when the Target List is deleted.

Actual Behavior

The date_modified isn't updated, that can be confusing

Possible Fix

https://github.com/SalesAgility/SuiteCRM/blob/master/modules/ProspectLists/ProspectList.php#L429-L430

Update the date_modified here.

Steps to Reproduce

1. Create a Target List
2. Add Contact records
3. Delete Target Lists
4. Check in the DB that the date_modified of the table "prospect_lists_prospects" of those records hasn't been updated

Context

This can be problematic if you are observing that date field
