Unsupported operation exception when java method overrides a property

[yigit]

When a java method overrides a kotlin property declaration, calling javaMethod.asMemberOf(javaType) throws unsupported operation exception.

e.g.

interface MyKotlinInterface {
    val x:Int
    var y:Int
}

class JavaImpl implements MyKotlinInterface { // remove implements and it will work fine
    public int getX() {
        return 1;
    }
    public int getY() {
        return 1;
    }
    public void setY(int value) {
    }
}

This test throws the exception:

resolver.getClassDeclarationByName("JavaImpl").let { javaImplDecl ->
            checkNotNull(javaImplDecl)
            val getX = javaImplDecl.getDeclaredFunctions().first { it.simpleName.asString() == "getX" }
            results.add(getX.asMemberOf(javaImplDecl.asStarProjectedType()).toSignature())
        }

This might be related to #248 but not sure. Hit this while updating Room to beta01.
