Add patch for revalidation button in status UI to handle missing form

• Add patch for revalidation button in status UI to handle missing form

A recent patch made it so that the eca validation lookup isn't always present on the page, which caused an issue with the Javascript on the page that would handle the revalidation logic. This change adds a check that the element exists before processing.
