Support partial route containing only the "from" for RouteBuilderParser.parseRouteBuilderTree

currently, if I have

public class PartialRoute extends RouteBuilder {

    public void configure() {
        from("file:src/data?noop=true");
    }
}

the org.apache.camel.parser.RouteBuilderParser.parseRouteBuilderTree(JavaClassSource, String, String, boolean) method is returning an empty list.

i'm expecting that i tis returning a list of one element with the "from"
