The tourist is still enroute in that picture (in a ship named "KSS Shuttle"). However, putting them onboard does not make a difference.
I've created a KSP.log by deleting the old one, starting up the game fresh, loading up the save with the task in the state as shown in my post above, then exiting the game again. I hope that is good enough. For good measure I have also added the save file itself, as well as my .ckan file for the mods I used in that save (I use no non-CKAN mods at this time).
Here's the files:

I ultimately resolved the situation by aborting those tasks. I could re-take the station crew one immediately so I was able to complete that, but the tourist got a free ride. I've not seen another similar situation to this.
