Edit Review / Add Content dialog not showing for a review creator that is not a participant

Steps to reproduce

• Create a review that you're not assigned as an author, moderator nor reviewer e.g. create a review for other user's commit (from Fisheye changeset view or via JIRA development panel) in a project where you're not a default moderator nor reviewer

Expected behavior

• You get an Edit Review or Add Content dialog (depending on whether the review is empty or not)

Actual behavior

• Edit Review / Add Content dialog is not shown
