This feels really sucky, seeing as I am the one that asked for these checks to be implemented..

### Please describe the problem.

--clean-duplicates now refuses to remove a file due to not being able to verify its presence in the local repo, even though it is present in the local repo and git-annex knows it is present (whereis and fsck on the keys complete correctly).

### What steps will reproduce the problem?

See transcript

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

git-annex versions:
* 2015-05-08
* 2015-05-28

OS: Arch Linux

### Please provide any additional information below.
