Bug 16978: Followup - Copy create_report permissions for delete_report

This patch should deal with comment #6's point of where a user who
has create, but not execute permissions, would lose delete ability.
Users with create and execute permissions would already have delete
as well.

TEST PLAN
---------
 1) Back up db
 2) drop database koha_library;
 3) create database koha_library;
 4) web install with all sample data with system user
 6) log into staff client as system user
 7) make sample koha admin user a superlibrarian
 8) set username and password for sample koha admin user
 9) log out and log in as koha admin
10) Create a user (USER_A) with permissions:
        create_reports   and execute_reports.
11) Create a user (USER_B) with permissions:
        create_reports,  but not execute_reports.
12) Create a user (USER_C) with permissions:
        execute_reports, but not create_reports.
13) Create a user (USER_D) with no report permissions.
14) Run the atomic update.
15) Check USER_A permissions
    -- should have delete_reports
16) Check USER_B
    -- should have delete_reports
17) Check USER_C
    -- should NOT have delete_reports
18) Check USER_D
    -- should NOT have delete_reports
19) run koha qa test tools
20) restore db
