Blame annotations for uncommitted changes - incorrect behaviour of buttons

[MetRonnie]

Description

When you have uncommitted changes, the "Open changes with previous revision" & "Open blame prior to this change" buttons open completely the wrong diff & blame.

Expected behaviour is that it opens the diff of uncommitted changes and the blame of the file as it is on HEAD, respectively.
