With a151116, we ignore action cache entry when checking the remote cache if a mandatory output of the Spawn is missing. However, this breaks Spawns that declare a directory output but don't generate anything under it. Since remote servers typically don't create directory ahead of time, and if the action itself doesn't create files under the directory, that directory will be eliminated from the action cache entry. This PR fixes that by not checking TreeArtifact output. Closes bazelbuild#15077. PiperOrigin-RevId: 436163970 (cherry picked from commit f585783)
