Bugfix: Do not crash while running the cleanup-chunks command

Previously, when you run the cleanup-chunks command, any unhandled exception
could crash the command. If this happened, there could be chunks that weren't
deleted.

Now, the command runs through all the chunks. If some chunks give problems,
a message is displayed indicating what error happened in which file.
