Renaming a constant uses the fully qualified name unnecessarily

If I rename a constant field in a xtend class it will refactor the source to use the FQN of that field even when it's not necessary.

Example:

package hello

class HelloWorld {
    
    static val MESSAGE = 'Hello World'
    
    def static main(String[] args) {
        println(MESSAGE)
    }
    
}

If I refactor MESSAGE to TEST the result is:

package hello

class HelloWorld {
    
    static val TEST = 'Hello World'
    
    def static main(String[] args) {
        println(hello.HelloWorld.TEST)
    }
    
}

The expected result is:

package hello

class HelloWorld {
    
    static val TEST = 'Hello World'
    
    def static main(String[] args) {
        println(TEST)
    }
    
}

Live demo:

The issue names no source file or test. Start by reproducing the constant-rename example in an Xtend class, then trace the rename refactoring entry point. Done means the renamed reference remains TEST rather than becoming hello.HelloWorld.TEST.
