Wrong state is shown on issue popovers

When the GraphQL request for issue popover fails, we always show the "Open" state.

Steps to reproduce

1. Create a closed issue in project-a
2. In another project's issue, create a comment with a reference to the previous issue. (e.g. project-a#1)
3. Rename project-a to project-b
4. Hover over the comment's reference and the popover now shows an incorrect "Open" state
