build i0608-0800

During #shutdown we clean the garbage from the history store by removing all
blobs which aren't referenced. This is done by collecting all the blobs with a
reference and then removing the rest.

We should be doing the reverse. We should keep track of "potential blobs to
remove" and then on shutdown ensuring that they don't have references and then
remove them.

Fixed and released to HEAD.
