gemu-test - test for sync_missing and dry-run
Fixed: Dry-run with restore completed was crashing.

fixed a bug introduced in v0.971 commit 7a29be90e7181e0e1bfe4b52fc0b37c4ad0f9e93
dry-run and restore-completed used archive_id instead of relative filename and thus was crashing with message:

UNEXPECTED ERROR: SOMEARCHIVEID not found in journal at /home/prj/mt/src/lib/App/MtAws/Journal.pm line 247.

you also can see that $j->latest($_) was called twice, this is a sign of bad code/bug.
gemu-test fixed  - filter value can be zero
gemu-test dry-run for download command implemented
