If an order has been partially served (has gotten as far as the summary page) clicking on the case number takes you to the summary page. If an order has not been started, click case number takes you to order upload page.

• [x] Clicking the case number of an unserved case takes you to the summary page Given that I am on the dashboard page When I click on a case number where that case has made it to the summary page without being served Then I am taken to the summary page

• [x] Clicking the case number of an unserved case takes you to the summary page Given that I am on the dashboard page When I click on a case number where that case hasn't made it to the summary page Then I am taken to the order upload page (start from scratch)

---

• [x] Given that I am on the dashboard page when I click on a case number that was partially served using the old flow Then I am taken to the order upload page to re-supply the word version of the order

---

• [x] Given that I am on the order upload page for an order that was partially served using the old flow And I have uploaded a valid word document When I click continue Then I am taken to the summary page where any previously uploaded supporting documents are still there

Another day of trying to get Panther testing working but no luck. Once @TomTucka and @hansnqyr are back I'll tap into the hive mind but for now, I'll park this and move on to a new ticket. The dev work is there for the changes we need - just the testing that's outstanding.

PR for this is ready to go as far as new functionality and tests go. Existing behat tests are broken and I'm not putting the time in to update until we know if this feature is going to be released pending feedback from legal re: using word docs to serve OPG rather than scanned sealed tiff.
