Java Companion not detected unless connecting HtmlImport is the first in the list

[anssit]

Steps to reproduce

1. Create a new Flow template, foo-bar.html with a companion class
2. Verify that FooBar.java is connected to the template
3. Close the template
4. Open FooBar.java and add a HtmlImport before the one pointing to foo-bar.html, for example

import com.vaadin.flow.templatemodel.TemplateModel;
import com.vaadin.flow.component.Tag;
import com.vaadin.flow.component.dependency.HtmlImport;
import com.vaadin.flow.component.polymertemplate.PolymerTemplate;

@Tag("foo-bar")
@HtmlImport("styles/shared-styles.html")
@HtmlImport("frontend://src/foo-bar.html")
public class FooBar extends PolymerTemplate<FooBar.FooBarModel> {

    public interface FooBarModel extends TemplateModel {

    }
}

5. Open foo-bar.html
