Sometimes issues will be moved between projects. The Commit linked to these issues will no longer be associated to the Issue, as the DVCS connector only checks if the current Issue Key is linked to a changeset.

To improve with moved issues, it should also check the moved_issue_key table (perhaps on manual resync) and link up the commits to the updated issue key.

This will preserve the full commit history, even if the issue is moved around projects for any reason.
