run.pid has wrong PID after auto-update

[TRM13]

After an auto-update the run.pid file has the old PID in it.

Before auto update:
qortal$ cat run.pid
936

After auto update:
qortal$ ps -ef | grep java
qortal 15685 1 38 Oct10 ? 07:53:50 /usr/lib/jvm/java-11-openjdk-amd64/bin/java -Djava.net.preferIPv4Stack=false -jar qortal.jar

qortal$ cat run.pid
936

This is because the PID changes and the PID in the run.pid file is created by start.sh... when re-started after auto-update start.sh is not utilized, therefore run.pid isn't updated.
