Resolves#4113
## Description:
Warships now reject the PatrolTile change when the new one is a
different water component.
Adds a test ensuring this behavior.
## Please complete the following:
- [x] I have added screenshots for all UI updates
There are none
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
No texts
- [x] I have added relevant tests to the test directory
I also have tested in game and tested that the test does indeed fail if
my fix is not present.
