Subject: [PATCH] Fix checking for restart files (#1186)

Undoes the portion of PR #1179 that caused a new bug while attempting to fix #1140, without removing the linter fixes. Instead `/dev/null` is 'searched' if `${RSTDIR_ATM}` is not defined. That situation will always result in zero files found, ensuring a rerun is not triggered.

Fixes #1140
Fixes #1185
Moots #1190
