Repo Size Remains constant after stripping all revisions (BB-1138)

I foolishly committed a large binary file early in my revision history, and wanted to remove it. I locally used hg convert with a file list to get rid of it, but I needed to clean the bitbucket repo and push the fresh copy. Upon stripping all the changesets, the reported size of my project remained unchanged despite having 0 reported changesets.

This could indicate either an error in size reporting, or an error in how space is reclaimed after stripping.
