Verified the patch "2482857-50.patch" mentioned in #50.
Steps performed to verify the patch:
1. Created a Book page "Parent Node"
2. Created child nodes "Child Node 1" and "Child Node 2".
3. Deleted the "Parent Node" , while deleting got an error "The website encountered an unexpected error. Please try again later." on a second attempt it got deleted
4. Accessed "Child Node 1" and "Child Node 2" and didn't get any error.
5. Applied the patch and repeated steps 1 to 4 with book names as "Patch_retest_Parent Node" and child nodes as "Patch retest_Child Node" and "Patch retest_Child Node 2"
6. "Patch_retest_Parent Node" got deleted without any exception error and I am able to access "Patch retest_Child Node" and "Patch retest_Child Node 2" without any fatal error.
7. No error is displayed for "Child Node 1" (the child page created before applying the patch).
So, issue can be marked as "PASSED" for errors and warnings.
