Fixed CoQ loop if a space playfield.yaml has drones but no patrol vessels [7719]

Build: 3203
Mode: Survival
Mode: Single Player

SERVER NAME: NA
SEED-ID: 1234

If applicable:
MODIFIED PLAYFIELDS: Yes

Reproducibility: Always
Severity: Major

Type: Playfield

Summary: If a space playfield uses a playfield.yaml and has drones setup but no AI patrol vessels or freighters, then entering the playfield causes a CoQ loop.


Description:
If a space playfield uses a fixed playfield.yaml file, has a drone base with random patrolling drones, and does not have any freighters or orbital patrols listed, then entering the playfield causes a CoQ loop.
Previously to 1.3, this worked fine.


Steps to Reproduce:
Tested in both a custom scenario and default survival using seed 1234.

Start a new default survival game using seed 1234 on the Temperate starting planet.
Fully exit the game after leaving your escape pod.
Go to your save game folder and find the template file for the orbit of the planet you started on. For example, NewGame/Templates/Owu Sector
Edit the playfield.yaml for the orbit.
Remove or comment out all the entries for the patrol vessels or freighters like so:

Leave the entries for the random patrolling drones.

Start Empyrion and resume your save game.
Fly or teleport to the orbit of your starting planet.
There will be a CoQ error loop.

This is reproducible also when starting a new game in a custom scenario that uses a playfield.yaml for a space playfield that has drones but no freighters or patrol vessels. Adding a single freighter to the playfield.yaml fixed the error in testing.
First reported in the 'Sphere Access 1' playfield of Project Eden on the workshop. Reproduced in default survival by editing the playfield.yaml of the save game.
