Access to Memory (AtoM)

To reproduce

1. Make sure the AtoM worker is running, e.g. sudo service atom-worker status
2. Login as an administrator, go to "Admin > Settings > Site information"
3. Change the "Site title" and click "Save"
4. Perform any action that runs a background job, e.g. Navigate to an archival description and click "Generate a finding aid", or change the name of an archival institution linked to one or more archival descriptions

Resulting error

2019/07/11 17:35:04 [error] 561#561: *13 FastCGI sent in stderr: "PHP message:
No Gearman worker available that can handle the job arFindingAidJob" while
reading response header from upstream, client: 10.10.10.1, server: _, request:

Expected result

Changing the site title should not affect the job scheduler functionality.

Additional notes

- Restarting the atom-worker will load the new site title and restore job scheduler functionality
- If the "Site title" is translated to a second language, switching the site to that culture will cause the job scheduler to fail as well, as the site title is different (this was the originally reported failure case)
- Changing the "Site Base URL" will also prevent the job scheduler from working
