Implicit getter and setter accesses not shown in Call Hierarchy

[mauromol]

Something like a follow-up to #489.
Consider the following Java class:

package test22;
public class MyBean {
	private String foo;
	public void setFoo(String foo) {
		this.foo = foo;
	}
	public String getFoo() {
		return foo;
	}
}

And the following Groovy class:

package test22

import groovy.transform.CompileStatic

@CompileStatic
class Test22 {
	public Test22() {
		def b = new MyBean(foo: 'c')
		b.foo = 'foo'
		def c = b.foo
	}
}

Invoke Call Hierarchy on MyBean.setFoo(String): I would expect to see references from def b = new MyBean(foo: 'c') and b.foo = 'foo'. However, I just see the first (thanks to #489), not the second.

Invoke Call Hierarchy on MyBean.getFoo(): I would expect to see references from def c = b.foo, but I don't see it.

org.eclipse.jdt.groovy.search.MethodReferenceSearchRequestor.acceptASTNode(ASTNode, TypeLookupResult, IJavaElement) finds the desired reference, but returns it as an "inaccurate" match and so the Call Hierarchy does not show it.

This works well in 3.1.0.xx-201809022023-e47! This is a great improvement, thank you! 👍
