Early arrival dialogue issue is fixed in patch 0.0.2

Hey,

Had an annoying issue whereas arriving at a delivery destination before the trip dialogue had ended would cause some issues.

• Firstly, that the trip dialogue (the bulk of the story) would be cut off for the end of trip dialogue.
• Secondly, this caused a soft lock. You would be unable to click on new delivery in the terminal...

This is fixed now! Arriving at a delivery destination early gives more expected behaviour. You can finish the remained of the trip dialogue before moving on to the ending dialogue. The ship also parks itself you would expect.

I've also cleaned up how I handle dialogue nodes in the backend. So they won't hang around longer than needed.

Note that I've only tested this for Jessie's first job. I don't think it should cause issues elsewhere (perhaps with multiple-choice options during the delivery stage???) If you have any issues let me know!

Thanks!
