[Koha] Follow up problem with bug number 30912

[Keith Sorbo]

I was having problems updating that seemed, initially, to be resolved when
I applied the changes made for bugfix 30912 (
https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=135958).

I ran the web update and it timed out several times on the Updating
Database Structure step.

Now I am getting the following error message. My installation is out of
service until I can resolve this issue.

Thanks!
