Issue description
Projects initiated from the world map appear when clicking on the shipyard:

Clicking the red X button doesn't abandon projects, so they will just sit there until fulfilled.
Expected behavior
Clicking the red X button should abandon the project and make it disappear until the player initiates it again from the world map.
Reproduction steps
- Initiate a settlement request from the world map (e.g. providing 100 construction II parts)
- View the request by clicking on your cargo shipyard
- Click the X button to abandon the project
- Nothing happens (the project doesn't disappear)
Game version
