### Please describe the problem.

git annex commands with `--all` option in tuned repository (with `annex.tune.branchhash1=true`) do not do anything.

### What steps will reproduce the problem?

1. Initialize a tuned annex repository with `git annex init -c annex.tune.branchhash1=true`.
2. Add some files to annex.
3. Now `git annex whereis --all` and `git annex fsck --all` (and maybe other commands) don't show/do anything.

### What version of git-annex are you using? On what operating system?

Version 7.20191230-g985373f8e, compiled from sources, on Debian buster 10.2.

### Please provide any additional information below.

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Of course, I love it! Great project, thanks, Joey!

However, /me always wants more features from it. It's great that git-annex continues to develop.
