Drop stale entries from the digest pending list

The digest guard test is red on main: #955 added
crawlers/gradle_cache.rs, patch/jvm_jar.rs and
patch/sidecars/maven.rs to the pending list, and #690 had already
moved them onto the utils::digest helpers. This ports the same
three-line change as #1016, so it becomes a no-op once #1016 lands.

(cherry picked from commit d65c5c4)
