You're right. It did feel a bit wrong. In v2, I'll replace this commit 
with a refactor of clear_midx_file() to do that. One tricky part is that 
we need to clear the file even if the in-memory struct hasn't been 
initialized, but I think passing a repository will suffice for that.

CC Stefan: Is there a plan to make get_object_directory() take a 
repository parameter?
