bugfix: SAMs targeting not updating owner after capture (#1838)

## Description:

After a SAM was captured, SAMTargetingSystem's player was not updated,
so it thought it was still owned by the original player. So it wouldn't
shoot down nukes launched from the original owner.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced

## Please put your Discord username so you can be contacted if a bug or
regression is found:
