Upgrading to 8.x-2.x fails if hash is NULL in the DB

When processing lingotek_update_8011() for update from Lingotek 8.x-1.12 to 8.x-2.0-rc1, the update process errors with the following error and the update aborts and lingotek_update_8011() can not completely process, which leaves the site unresponsive with "Base table or view not found: 1146 Table 'manh_mcdev.lingotek_metadata' doesn't exist" reported in logs.

Here's the exact error message. going to continue looking into this. Based on the update hook number, I think this is a 8.x.1.x issue. I think the site db I'm working had previously updated the code, but the update hook never processed completely. The lingotek_temporary_content_metadata table exists already.
